+
+<h1>vboot - Verified Boot Support</h1>
+
+<p>
+Google's verified boot support consists of:
+</p>
+<ul>
+  <li>A root of trust</li>
+  <li>Special firmware layout</li>
+  <li>Firmware verification</li>
+  <li>Firmware measurements</li>
+  <li>A firmware update mechanism</li>
+  <li>Specific build flags</li>
+  <li>Signing the coreboot image</li>
+</ul>
+
+Google's vboot verifies the firmware and places measurements
+within the TPM.
+
+<hr>
+<h2>Root of Trust</h2>
+<p>
+When using vboot, the root-of-trust is basically the read-only portion of the
+SPI flash.  The following items factor into the trust equation:
+</p>
+<ul>
+  <li>The GCC compiler must reliably translate the code into machine code
+      without inserting any additional code (virus, backdoor, etc.)
+  </li>
+  <li>The CPU must reliably execute the reset sequence and instructions as
+      documented by the CPU manufacturer.
+  </li>
+  <li>The SPI flash must provide only the code programmed into it to the CPU
+      without providing any alternative reset vector or code sequence.
+  </li>
+  <li>The SPI flash must honor the write-protect input and protect the
+      specified portion of the SPI flash from all erase and write accesses.
+  </li>
+</ul>
+
+<p>
+The firmware is typically protected using the write-protect pin on the SPI
+flash part and setting some of the write-protect bits in the status register
+during manufacturing.  The protected area is platform specific and for x86
+platforms is typically 1/4th of the SPI flash
+part size.  Because this portion of the SPI flash is hardware write protected,
+it is not possible to update this portion of the SPI flash in the field,
+without altering the system to eliminate the ground connection to the SPI flash
+write-protect pin.  Without hardware modifications, this portion of the SPI
+flash maintains the manufactured state during the system's lifetime.
+</p>
+
+<hr>
+<h2>Firmware Layout</h2>
+<p>
+Several sections are added to the firmware layout to support vboot:
+</p>
+<ul>
+  <li>Read-only section</li>
+  <li>Google Binary Blob (GBB) area</li>
+  <li>Read/write section A</li>
+  <li>Read/write section B</li>
+</ul>
+<p>
+The following sections describe the various portions of the flash layout.
+</p>
+
+<h3>Read-Only Section</h3>
+<p>
+The read-only section contains a coreboot file system (CBFS) that contains all
+of the boot firmware necessary to perform recovery for the system. This
+firmware is typically protected using the write-protect pin on the SPI flash
+part and setting some of the write-protect bits in the status register during
+manufacturing.  The protected area is typically 1/4th of the SPI flash part
+size and must cover the entire read-only section which consists of:
+</p>
+<ul>
+  <li>Vital Product Data (VPD) area</li>
+  <li>Firmware ID area</li>
+  <li>Google Binary Blob (GBB) area</li>
+  <li>coreboot file system containing read-only recovery firmware</li>
+</ul>
+
+<h3>Google Binary Blob (GBB) Area</h3>
+<p>
+The GBB area is part of the read-only section.  This area contains a 4096 or
+8192 bit public root RSA key that is used to verify the VBLOCK area to obtain
+the firmware signing key.
+</p>
+
+<h3>Recovery Firmware</h3>
+<p>
+The recovery firmware is contained within a coreboot file system and consists
+of:
+</p>
+<ul>
+  <li>reset vector</li>
+  <li>bootblock</li>
+  <li>verstage</li>
+  <li>romstage</li>
+  <li>postcar</li>
+  <li>ramstage</li>
+  <li>payload</li>
+  <li>flash map file</li>
+  <li>config file</li>
+  <li>processor specific files:
+    <ul>
+      <li>Microcode</li>
+      <li>fspm.bin</li>
+      <li>fsps.bin</li>
+    </ul>
+  </li>
+</ul>
+
+<p>
+The recovery firmware is written during manufacturing and typically contains
+code to write the storage device (eMMC device or hard disk).  The recovery
+image is usually contained on a socketed device such as a USB flash drive or
+an SD card.  Depending upon the payload firmware doing the recovery, it may
+be possible for the user to interact with the system to specify the recovery
+image path.  Part of the recovery is also to write the A and B areas of the
+SPI flash device to boot the system.
+</p>
+
+
+<h3>Read/Write Section</h3>
+
+<p>
+The read/write sections contain an area which contains the firmware signing
+key and signature and an area containing a coreboot file system with a subset
+of the firmware.  The firmware files in FW_MAIN_A and FW_MAIN_B are:
+</p>
+<ul>
+  <li>romstage</li>
+  <li>postcar</li>
+  <li>ramstage</li>
+  <li>payload</li>
+  <li>config file</li>
+  <li>processor specific files:
+    <ul>
+      <li>Microcode</li>
+      <li>fspm.bin</li>
+      <li>fsps.bin</li>
+    </ul>
+  </li>
+</ul>
+
+<p>
+The firmware subset enables most issues to be fixed in the field with firmware
+updates.  The firmware files handle memory and most of silicon initialization.
+These files also produce the tables which get passed to the operating system.
+</p>
+
+<hr>
+<h2>Firmware Updates</h2>
+<p>
+The read/write sections exist in one of three states:
+</p>
+<ul>
+  <li>Invalid</li>
+  <li>Ready to boot</li>
+  <li>Successfully booted</li>
+</ul>
+
+<table border="1">
+<tr bgcolor="#ffc0c0">
+<td>
+Where is this state information written?
+<br/>CMOS?
+<br/>RW_NVRAM?
+<br/>RW_FWID_*
+</td>
+</tr>
+</table>
+
+<p>
+Firmware updates are handled by the operating system by writing any read/write
+section that is not in the "successfully booted" state.  Upon the next reboot,
+vboot determines the section to boot.  If it finds one in the "ready to boot"
+state then it attempts to boot using that section.  If the boot fails then
+vboot marks the section as invalid and attempts to fall back to a read/write
+section in the "successfully booted" state.  If vboot is not able to find a
+section in the "successfully booted" state then vboot enters recovery mode.
+</p>
+
+<p>
+Only the operating system is able to transition a section from the "ready to
+boot" state to the "successfully booted" state.  The transition is typically
+done after the operating system has been running for a while indicating
+that successful boot was possible and the operating system is stable.
+</p>
+
+<p>
+Note that as long as the SPI write protection is in place then the system is
+always recoverable.  If the flash update fails then the system will continue
+to boot using the previous read/write area.  The same is true if coreboot
+passes control to the payload or the operating system and then the boot fails.
+In the worst case, the SPI flash gets totally corrupted in which case vboot
+fails the signature checks and enters recovery mode.  There are no times where
+the SPI flash is exposed and the reset vector or part of the recovery firmware
+gets corrupted.
+</p>
+
+<hr>
+<h2>Build Flags</h2>
+<p>
+The following Kconfig values need to be selected to enable vboot:
+</p>
+<ul>
+  <li>COLLECT_TIMESTAMPS</li>
+  <li>VBOOT</li>
+</ul>
+
+<p>
+The starting stage needs to be specified by selecting either
+VBOOT_STARTS_IN_BOOTBLOCK or VBOOT_STARTS_IN_ROMSTAGE.
+</p>
+
+<p>
+If vboot starts in bootblock then vboot may be built as a separate stage by
+selecting VBOOT_SEPARATE_VERSTAGE.  Additionally, if static RAM is too small
+to fit both verstage and romstage then selecting VBOOT_RETURN_FROM_VERSTAGE
+enables bootblock to reuse the RAM occupied by verstage for romstage.
+</p>
+
+<p>
+Non-volatile flash is needed for vboot operation.  This flash area may be in
+CMOS, the EC, or in a read/write area of the SPI flash device.  Select one of
+the following:
+</p>
+<ul>
+  <li>VBOOT_VBNV_CMOS</li>
+  <li>VBOOT_VBNV_EC</li>
+  <li>VBOOT_VBNV_FLASH</li>
+</ul>
+<p>
+More non-volatile storage features may be found in src/vboot/Kconfig.
+</p>
+
+<p>
+A TPM is also required for vboot operation.  TPMs are available in
+drivers/i2c/tpm and drivers/pc80/tpm.
+</p>
+
+<p>
+In addition to adding the coreboot files into the read-only region, enabling
+vboot causes the build script to add the read/write files into coreboot file
+systems in FW_MAIN_A and FW_MAIN_B.
+</p>
+
+<hr>
+<h2>Signing the coreboot Image</h2>
+<p>
+The following command script is an example of how to sign the coreboot image file.
+This script is used on the Intel Galileo board and creates the GBB area and
+inserts it into the coreboot image.  It also updates the VBLOCK areas with the
+firmware signing key and the signature for the FW_MAIN firmware.  More details
+are available in 3rdparty/vboot/README.

+<h2>Boot Flow</h2>
+<p>
+The reset vector exist in the read-only area and points to the bootblock entry
+point.  The only copy of the bootblock exists in the read-only area of the SPI
+flash.  Verstage may be part of the bootblock or a separate stage.  If separate
+then the bootblock loads verstage from the read-only area and transfers control
+to it.
+</p>
+
+<p>
+Upon first boot, verstage attempts to verify the read/write section A.  It gets
+the public root key from the GBB area and uses that to verify the VBLOCK area
+in read-write section A.  If the VBLOCK area is valid then it extracts the
+firmware signing key (1024-8192 bits) and uses that to verify the FW_MAIN_A
+area of read/write section A.  If the verification is successful then verstage
+instructs coreboot to use the coreboot file system in read/write section A for
+the contents of the remaining boot firmware (romstage, postcar, ramstage and
+the payload).
+</p>
+
+<p>
+If verification fails for the read/write area and the other read/write area is
+not valid vboot falls back to the read-only area to boot into system recovery.

+<h2>Chromebook Special Features</h2>
+<p>
+Google's Chromebooks have some special features:
+</p>
+<ul>
+  <li>Developer mode</li>
+  <li>Write-protect screw</li>
+</ul>
+
+<h3>Developer Mode</h3>
+<p>
+Developer mode allows the user to use coreboot to boot another operating system.
+This may be a another (beta) version of Chrome OS, or another flavor of
+GNU/Linux.  Use of developer mode does not void the system warranty.  Upon
+entry into developer mode, all locally saved data on the system is lost.
+This prevents someone from entering developer mode to subvert the system
+security to access files on the local system or cloud.
+</p>
+
+<h3>Write Protect Screw</h3>
+<p>
+Chromebooks have a write-protect screw which provides the ground to the
+write-protect pin of the SPI flash.  Google specifically did this to allow
+the manufacturing line and advanced developers to re-write the entire SPI flash
+part.  Once the screw is removed, any firmware may be placed on the device.
+However, accessing this screw requires opening the case and voids the system
+warranty!

-# IPMI KCS driver
-
-The driver can be found in `src/drivers/ipmi/`. It works with BMC that provide
-a KCS I/O interface as specified in the [IPMI] standard.
-
-The driver detects the IPMI version, reserves the I/O space in coreboot's
-resource allocator and writes the required ACPI and SMBIOS tables.
-
-## For developers
-
-To use the driver, select the `IPMI_KCS` Kconfig and add the following PNP
-device under the LPC bridge device (in example for the KCS at 0xca2):
-
-```
- chip drivers/ipmi
-   device pnp ca2.0 on end         # IPMI KCS
- end
-```
-
-**Note:** The I/O base address needs to be aligned to 2.
-
-The following registers can be set:
-
-* `have_nv_storage`
-  * Boolean
-  * If true `nv_storage_device_address` will be added to SMBIOS type 38.
-* `nv_storage_device_address`
-  * Integer
-  * The NV storage address as defined in SMBIOS spec for type 38.
-* `bmc_i2c_address`
-  * Integer
-  * The i2c address of the BMC. zero if not applicable.
-* `have_apic`
-  * Boolean
-  * If true the `apic_interrupt` will be added to SPMI table.
-* `apic_interrupt`
-  * Integer
-  * The APIC interrupt used to notify about a change on the KCS.
-* `have_gpe`
-  * Boolean
-  * If true the `gpe_interrupt` will be added to SPMI table.
-* `gpe_interrupt`
-  * Integer
-  * The bit in GPE (SCI) used to notify about a change on the KCS.

-[architecture]: comparision_coreboot_uefi.svg
-
-## Stages
-coreboot consists of multiple stages that are compiled as separate binaries and
-are inserted into the CBFS with custom compression. The bootblock usually doesn't
-have compression while the ramstage and payload are compressed with LZMA.
-
-Each stage loads the next stage a given address (possibly decompressing it).
-
-Some stages are relocatable and can be placed anywhere in DRAM. Those stages are
-usually cached in CBMEM for faster loading times on ACPI S3 resume.
-
-Supported stage compressions:
-* none
-* LZ4
-* LZMA
-
-## bootblock
-The bootblock is the first stage executed after CPU reset. It is written in
-assembly language and its main task is to set up everything for a C-environment:
-
-Common tasks:
-
-* Cache-As-RAM for heap and stack
-* Set stack pointer
-* Clear memory for BSS
-* Decompress and load the next stage
-
-On x86 platforms that includes:
-
-* Microcode updates
-* Timer init
-* Switching from 16-bit real-mode to 32-bit protected mode
-
-The bootblock loads the romstage or the verstage if verified boot is enabled.
-
-### Cache-As-Ram
-The *Cache-As-Ram*, also called Non-Eviction mode, or *CAR* allows to use the
-CPU cache like regular SRAM. This is particullary usefull for high level
-languages like `C`, which need RAM for heap and stack.
-
-The CAR needs to be activated using vendor specific CPU instructions.
-
-The following stages run when Cache-As-Ram is active:
-* bootblock
-* romstage
-* verstage
-* postcar
-
-## verstage
-The verstage is where the root-of-trust starts. It's assumed that
-it cannot be overwritten in-field (together with the public key) and
-it starts at the very beginning of the boot process.
-The verstage installs a hook to verify a file before it's loaded from
-CBFS or a partition before it's accessed.
-
-The verified boot mechanism allows trusted in-field firmware updates
-combined with a fail-safe recovery mode.
-
-## romstage
-The romstage initializes the DRAM and prepares everything for device init.
-
-Common tasks:
-
-* Early device init
-* DRAM init
-
-## postcar
-To leave the CAR setup and run code from regular DRAM the postcar-stage tears
-down CAR and loads the ramstage. Compared to other stages it's minimal in size.
-
-## ramstage
-
-The ramstage does the main device init:
-
-* PCI device init
-* On-chip device init
-* TPM init (if not done by verstage)
-* Graphics init (optional)
-* CPU init (like set up SMM)
-
-After initialization tables are written to inform the payload or operating system
-about the current hardware existance and state. That includes:
-
-* ACPI tables (x86 specific)
-* SMBIOS tables (x86 specific)
-* coreboot tables
-* devicetree updates (ARM specific)
-
-It also does hardware and firmware lockdown:
-* Write-protection of boot media
-* Lock security related registers
-* Lock SMM mode (x86 specific)
-
-## payload
-The payload is the software that is run after coreboot is done. It resides in
-the CBFS and there's no possibility to choose it at runtime.
-
-For more details have a look at [payloads](../payloads.md).

-Display Panel Specifics
-=======================
-
-Timing Parameters
-----------------
-
-From the binary file `edid` in the sys filesystem on Linux, the panel can be
-identified. The exact path may differ slightly. Here is an example:
-
-```sh
-$ strings /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/edid
-@0 5
-LG Display
-LP140WF3-SPD1
-```
-
-To figure out the timing parameters, refer to the [Intel Programmer's Reference
-Manuals](https://01.org/linuxgraphics/documentation/hardware-specification-prms)
-and try to find the datasheet of the panel using the information from `edid`.
-In the example above, you would search for `LP140WF3-SPD1`. Find a table listing
-the power sequence timing parameters, which are usually named T[N] and also
-referenced in Intel's respective registers listing. You need the values for
-`PP_ON_DELAYS`, `PP_OFF_DELAYS` and `PP_DIVISOR` for your `devicetree.cb`:
-
-```eval_rst

-
-Intel GPU Tools and VBT
-----------------------
-
-The Intel GPU tools are in a package called either `intel-gpu-tools` or
-`igt-gpu-tools` in most distributions of Linux-based operating systems.
-In the coreboot `util/` directory, you can find `intelvbttool`.
-
-From a running system, you can dump the register values directly:
-```sh
-$ intel_reg dump --all | grep PCH_PP
-                      PCH_PP_STATUS (0x000c7200): 0x80000008
-                     PCH_PP_CONTROL (0x000c7204): 0x00000007
-                   PCH_PP_ON_DELAYS (0x000c7208): 0x07d00001
-                  PCH_PP_OFF_DELAYS (0x000c720c): 0x01f40001
-                     PCH_PP_DIVISOR (0x000c7210): 0x0004af06
-```
-
-You can obtain the timing values from a VBT (Video BIOS Table), which you can
-dump from a vendor UEFI image:
-```sh
-$ intel_vbt_decode data.vbt | grep T3
-                Power Sequence: T3 2000 T7 10 T9 2000 T10 500 T12 5000

-# Flashmap and Flashmap Descriptor in coreboot
-
-## Flashmap
-
-[Flashmap](https://code.google.com/p/flashmap) (FMAP) is a binary format to
-describe partitions in a flash chip. It was added to coreboot to support the
-requirements of Chromium OS firmware but then was also used in other scenarios
-where precise placement of data in flash was necessary, or for data that is
-written to at runtime, as CBFS is considered too fragile for such situations.
-The Flashmap implementation inside coreboot is the de facto standard today.
-
-Flashmap partitions the image into clearly delimited sections and some of those
-sections may be CBFSes that can hold arbitrary-length files (at least one, the
-default CBFS, called `COREBOOT`). General guidance is that everything with
-strict layout requirements (e.g. must be aligned to erase blocks or
-something else) should have its own Flashmap section, and everything else should
-normally go into CBFS.
-
-The Flashmap itself starts with a header `struct fmap` and followed by a list of
-section descriptions in `strcut fmap_area`.
-
-### Header
-The header `struct fmap` has following fields:
-* `signature`: 8 characters as `"__FMAP__"`.
-* `ver_major`: one byte for major version (currently only 1).
-* `ver_minor`: one byte for minor version (current value is 1).
-* `base`: 64 bit integer for the address of the firmware binary.
-* `size`: 32 bit integer for the size of firmware binary in bytes.
-* `name`: 32 characters for the name of the firmware binary.
-* `nareas`: 16 bit integer for the number of area definitions (i.e., how many
-  sections are in this firmware image) following the header.
-
-### Area Definition
-The section is defined by `struct fmap_area` with following fields:
-* `offset`: 32 bit integer for where the area starts (relative to `base` in
-  header).
-* `size`: 32 bit integer for the size of area in bytes.
-* `name`: 32 characters for a descriptive name of this area. Should be unique to
-  all sections inside same Flashmap.
-* `flags`: 16 bit integer for attributes of this area (see below).
-
-### Area Flags
-Currently the defined values for `flags` in `struct fmap_area` are:
-* `FMAP_AREA_PRESERVE`: suggesting the section should be preserved when
-  updating firmware, usually for product data like serial number, MAC address,
-  or calibration and cache data.
-* `FMAP_AREA_STATIC`: Not really used today.
-* `FMAP_AREA_COMPRESSED`: Not really used today.
-* `FMAP_AREA_RO`: Not really used today.
-
-### FMAP section
-The whole Flashmap (`struct fmap` and list of `struct fmap_area`) should be
-stored in a standalone section named as `FMAP` (which should be also described
-by the Flashmap itself in `struct fmap_area`). There's no restriction for where
-it should be located (or how large), but usually we need to do a linear or
-binary search on whole firmware binary image to find Flashmap so a properly
-aligned address would be better.
-
-### COREBOOT section
-coreboot firmware images (`coreboot.rom`) should have at least one Flashmap
-section that is reserved for CBFS. Usually it is named as `COREBOOT`.
-
-## Flashmap Descriptor
-
-Since coreboot is starting to use a "partition" of Flashmap to describe the
-flash chip layout (both at runtime and when flashing a new image onto a
-chip), the project needs a reasonably expressive plain text format for
-representing such sections in the source tree.
-
-Flashmap Descriptor (FMD) is a [language and
-compiler](https://chromium-review.googlesource.com/#/c/255031) inside coreboot
-utility folder that can be used to generate final firmware images (i.e.
-`coreboot.rom`) formatted by Flashmap.
-
-The FMD implementation is in coreboot `utils/cbfstool` folder. Here's an
-informal language description:
-
-```
-# <line comment>
-<image name>[@<memory-mapped address>] <image size> {
-    <section name>[(flags)][@<offset from start of image>] [<section size>] [{
-        <subsection name>[@<offset from start of parent section>] [<subsection size>] [{
-            # Sections can be nested as deeply as desired
-            <subsubsection name>[(flags)][@...] [...] [{...}]
-        }]
-        [<subsection name>[(flags)][@...] [...] [{...}]]
-        # There can be many subsections at each level of nesting: they will be inserted
-        # sequentially, and although gaps are allowed, any provided offsets are always
-        # relative to the closest parent node's and must be strictly increasing with neither
-        # overlapping nor degenerate-size sections.
-    }]
-}
-```
-
-Note that the above example contains a few symbols that are actually meta
-syntax, and therefore have neither meaning nor place in a real file. The `<.*>`s
-indicate placeholders for parameters:
-
-* The names are strings, which are provided as single-word (no white space)
-  groups of syntactically unimportant symbols (i.e. every thing except `@`, `{`,
-  and `}`): they are not surrounded by quotes or any other form of delimiter.
-* The other fields are non-negative integers, which may be given as decimal or
-  hexadecimal; in either case, a `K`, `M`, or `G` may be appended (without
-  intermediate white space) as a multiplier.
-* Comments consist of anything one manages to enter, provided it doesn't start a
-  new line.
-
-The `[.*]`s indicate that a portion of the file could be omitted altogether:
-
-* Just because something is noted as optional doesn't mean it is in every case:
-  the answer might actually depend on which other information is---or
-  isn't---provided.
-* The "flag" specifies the attribute or type for given section. The most
-  important supported flag is "CBFS", which indicates the section will contain
-  a CBFS structure.
-* In particular, it is only legal to place a (CBFS) flag on a leaf section; that
-  is, choosing to add child sections excludes the possibility of putting a CBFS
-  in their parent. Such flags are only used to decide where CBFS empty file
-  headers should be created, and do not result in the storage of any additional
-  metadata in the resulting FMAP section.
-
-Additionally, it's important to note these properties of the overall file and
-its values:
-
-* Other than within would-be strings and numbers, white space is ignored. It
-  goes without saying that such power comes with responsibility, which is why
-  this sentence is here.
-* Although the `section name` must be globally unique, one of them may (but is
-  not required to) match the image name.
-* It is a syntax error to supply a number (besides 0) that begins with the
-  character `0`, as there is no intention of adding octals to the mix.
-* The image's memory address should be present on (and only on) layouts for
-  memory-mapped chips.
-* Although it may be evident from above, all `section` offsets are relative only
-  to the immediate parent. There is no way to include an absolute offset (i.e.
-  from the beginning of flash), which means that it is "safe" to reorder the
-  sections within a particular level of nesting, as long as the change doesn't
-  cause their positions and sizes to necessitate overlap or zero sizes.
-* A `section` with omitted offset is assumed to start at as low a position as
-  possible (with no consideration of alignment) and one with omitted size is
-  assumed to fill the remaining space until the next sibling or before the end
-  of its parent.
-* It's fine to omit any `section`'s offset, size, or both, provided its position
-  and size are still unambiguous in the context of its *sibling* sections and
-  its parent's *size*. In particular, knowledge of one .*section 's children or
-  the `section`s' common parent's siblings will not be used for this purpose.
-* Although `section`s are not required to have children, the flash chip as a
-  whole must have at least one.
-* Though the braces after `section`s may be omitted for those that have no
-  children, if they are present, they must contain at least one child.
-
-To see the formal description of the language, please refer to the Lex and Yacc
-files: `fmd_scanner.l` and `fmd_scanner.y`.

-
-## Building coreboot
-
-The following steps set the default parameters for this board to build a
-fully working image:
-
-```bash
-make distclean
-touch .config
-./util/scripts/config --enable VENDOR_ASROCK
-./util/scripts/config --enable BOARD_ASROCK_H110M_DVS
-./util/scripts/config --enable CONFIG_ADD_FSP_BINARIES
-./util/scripts/config --enable CONFIG_FSP_USE_REPO
-./util/scripts/config --set-str REALTEK_8168_MACADDRESS "xx:xx:xx:xx:xx:xx"
-make olddefconfig
-```
-
-However, it is strongly advised to use `make menuconfig` afterwards
-(or instead), so that you can see all of the settings.
-
-Use the following command to disable the serial console if debugging
-output is not required:
-
-```bash
-./util/scripts/config --disable CONSOLE_SERIAL
-```
-
-However, a more flexible method is to change the console log level from
-within an OS using `util/nvramtool`, or with the `nvramcui` payload.
-
-Now, run `make` to build the coreboot image.
-
-## Flashing coreboot
-
-### Internal programming
-
-The main SPI flash can be accessed using [flashrom]. By default, only
-the BIOS region of the flash is writable. If you wish to change any
-other region, such as the Management Engine or firmware descriptor, then
-an external programmer is required (unless you find a clever way around
-the flash protection). More information about this [here](../../flash_tutorial/index.md).
-
-### External programming
-
-The flash chip is a 8 MiB socketed DIP-8 chip. Specifically, it's a
-Macronix MX25L6473E, whose datasheet can be found [here][MX25L6473E].
-The chip is located to the bottom right-hand side of the board. For
-a precise location, refer to section 1.3 (Motherboard Layout) of the
-[H110M-DVS manual], where the chip is labelled "64Mb BIOS". Take note of
-the chip's orientation, remove it from its socket, and flash it with
-an external programmer. For reference, the notch in the chip should be
-facing towards the bottom of the board.
-
-## Known issues
-
- The VGA port doesn't work. Discrete graphic card is used as primary
-  device for display output (if CONFIG_ONBOARD_VGA_IS_PRIMARY is not
-  set). Dynamic switching between iGPU and PEG is not yet supported.
-
- SuperIO GPIO pin is used to reset Realtek chip. However, since the
-  Logical Device 7 (GPIO6, GPIO7, GPIO8) is not initialized, the network
-  chip is in a reset state all the time.

-### Internal programming
-
-The main SPI flash can be accessed using [flashrom].
-UEFI builds that allow flash chip access:
-> v5016 is untested, but expected to work as well
-> v5018
-> v5103
-> v5104
-> v5107
-> v5202
-> v6002
-> v6004
-> v6102

-> v6404 (requires downgrading to v6402 to flash coreboot)
-> v6501 (requires downgrading to v6402 to flash coreboot)
-> v6502 (requires downgrading to v6402 to flash coreboot)
-
-Build v6502, v6501 and v6404 do not allow access to the flash chip.
-Fortunately it is possible to downgrade build v6502, v6501, v6404 to v6402, with EZFlash.
-Downgrading is done by downloading build v6402 from ASUS' F2A85-M download page
-and copying it to (the root directory of) a FAT32 formatted USB flash drive.
-Enter the EFI setup, switch to advanced mode if necessary,
-open the 'Tool' tab and select "ASUS EZ Flash 2 Utility".

-    # dd if=/dev/mem of=vgabios.bin bs=1k count=64 skip=768
-
-### Option 2: Extract from the vendor binary
-
-Download the BIOS from the Support section at [ASUS F2A85-M].
-Using MMTool Aptio (versions 4.5.0 and 5.0.0):
- Load image, click on 'Extract tab'
- Select the 'export path' and 'link present' options
- Choose option ROM '1002,9900' and click on 'Extract'

-
-### Internal programming
-
-The main SPI flash can be accessed using [flashrom]. By default, only
-the BIOS region of the flash is writable. If you wish to change any
-other region (Management Engine or flash descriptor), then an external
-programmer is required.
-
-The following command may be used to flash coreboot:
-
-```
-$ sudo flashrom --noverify-all --ifd -i bios -p internal -w coreboot.rom
-```
-
-The use of `--noverify-all` is required since the Management Engine
-region is not readable even by the host.
-
-## Known issues
-
- There is no automatic, OS-independent fan control. This is because
-  the super I/O hardware monitor can only obtain valid CPU temperature
-  readings from the PECI agent, whose complete initialisation is not
-  publicly documented. The `coretemp` driver can still be used for
-  accurate CPU temperature readings.
-
- me_cleaner breaks LPC bus and attached components!
- PS/2 mouse doesn't work

-
-### Internal programming
-
-The main SPI flash cannot be written because Asus disables BIOSWE and
-enables BLE/SMM_BWP flags in BIOS_CNTL for their latest bioses.
-An external programmer is required. You must flash standalone,
-flashing in-circuit doesn't work. The flash chip is socketed, so it's
-easy to remove and reflash.
-

-  750Ti and FirePro W5100 under Mint 18.3/19.1)
-
-## Known issues
-
- The rear's USB3s on bottom (closest to the PCB) have problems booting or
-  being used before the OS loads. For better compatibility, please use
-  the Z77's ones above the Ethernet connector or the Asmedia's top one
-
- After S3 suspend, some USB3 connectors on rear seem not to work
-
- At the moment, the power led does not blink when entering S3 state
-
- Currently, we have not setup the SuperIO's Hardware Monitor (HWM),
-  so only the CPU sensors are reported
-
- If you use the MRC.bin, the NVRAM variable gfx_uma_size may be ignored
-  as IGP's UMA could be reconfigured by the blob
-
- Using TianoCore + a PCIe GPU under Windows crashes with an
-  ACPI_BIOS_ERROR fatal code, not sure why. Using just the IGP
-  works perfectly
-
- Under Windows 10, if you experiment problems with PS/2 devices, change
-  HKLM\SYSTEM\CurrentControlSet\Services\i8042prt->Start from '3' to '1'

-# HP EliteBook series
-
-This document is about HP EliteBook series laptops up to Ivy Bridge era
-which use SMSC KBC1126 as embedded controller.
-
-## EC
-
-SMSC KBC1098/KBC1126 has been used in HP EliteBooks for many generations.
-They use similar EC firmware that will load other code and data from the
-SPI flash chip, so we need to put some firmware blobs to the coreboot image.
-
-The following document takes EliteBook 2760p as an example.
-
-First, you need to extract the blobs needed by EC firmware using util/kbc1126.
-You can extract them from your backup firmware image, or firmware update
-provided by HP with [unar] as follows:
-
-```bash
-wget https://ftp.hp.com/pub/softpaq/sp79501-80000/sp79710.exe
-unar sp79710.exe
-${COREBOOT_DIR}/util/kbc1126/kbc1126_ec_dump sp79710/Rompaq/68SOU.BIN
-mv 68SOU.BIN.fw1 ${COREBOOT_DIR}/2760p-fw1.bin
-mv 68SOU.BIN.fw2 ${COREBOOT_DIR}/2760p-fw2.bin
-```
-
-When you config coreboot, select:
-
-```text
-Chipset --->
-  [*] Add firmware images for KBC1126 EC
-      (2760p-fw1.bin) KBC1126 firmware #1 path and filename
-      (2760p-fw2.bin) KBC1126 filename #2 path and filename
-```
-
-## Super I/O
-
-EliteBook 8000 series laptops have SMSC LPC47n217 Super I/O to provide
-a serial port and a parallel port, you can debug the laptop via this
-serial port.
-
-## porting
-
-To port coreboot to an HP EliteBook laptop, you need to do the following:
-
- select Kconfig option `EC_HP_KBC1126`
- select Kconfig option `SUPERIO_SMSC_LPC47N217` if there is LPC47n217 Super I/O
- initialize EC and Super I/O in romstage
- add EC and Super I/O support to devicetree.cb
-
-To get the related values for EC in devicetree.cb, you need to extract the EFI
-module EcThermalInit from the vendor UEFI firmware with [UEFITool]. Usually,
-`ec_data_port`, `ec_cmd_port` and `ec_ctrl_reg` has the following values:
-
- For xx60 series: 0x60, 0x64, 0xca
- For xx70 series: 0x62, 0x66, 0x81
-
-You can use [radare2] and the following [r2pipe] Python script to find
-these values from the EcThermalInit EFI module:
-
-```python
-#!/usr/bin/env python
-
-# install radare2 and use `pip3 install --user r2pipe` to install r2pipe
-
-import r2pipe
-import sys
-
-if len(sys.argv) < 2:
-    fn = "ecthermalinit.efi"
-else:
-    fn = sys.argv[1]
-
-r2 = r2pipe.open(fn)
-r2.cmd("aa")
-entryf = r2.cmdj("pdfj")
-
-for insn in entryf["ops"]:
-    if "lea r8" in insn["opcode"]:
-        _callback = insn["ptr"]
-        break
-
-r2.cmd("af @ {}".format(_callback))
-callbackf_insns = r2.cmdj("pdfj @ {}".format(_callback))["ops"]
-
-def find_port(addr):
-    ops = r2.cmdj("pdfj @ {}".format(addr))["ops"]
-    for insn in ops:
-        if "lea r8d" in insn["opcode"]:
-            return insn["ptr"]
-
-ctrl_reg_found = False
-
-for i in range(0, len(callbackf_insns)):
-    if not ctrl_reg_found and "mov cl" in callbackf_insns[i]["opcode"]:
-        ctrl_reg_found = True
-        ctrl_reg = callbackf_insns[i]["ptr"]
-        print("ec_ctrl_reg = 0x%02x" % ctrl_reg)
-        cmd_port = find_port(callbackf_insns[i+1]["jump"])
-        data_port = find_port(callbackf_insns[i+3]["jump"])
-        print("ec_cmd_port = 0x%02x\nec_data_port = 0x%02x" % (cmd_port, data_port))
-
-    if "mov bl" in callbackf_insns[i]["opcode"]:
-        ctrl_value = callbackf_insns[i]["ptr"]
-        print("ec_fan_ctrl_value = 0x%02x" % ctrl_value)
-```

-### Internal programming
-
-The SPI flash can be accessed using [flashrom].
-
-### External programming
-
-External programming with an SPI adapter and [flashrom] does work, but it powers the
-whole southbridge complex. You need to supply enough current through the programming adapter.
-
-If you want to use a SOIC pomona test clip, you have to cut the 2nd DRAM DIMM holder,
-as otherwise there's not enough space near the flash.

-## Installation instructions
-* The standard method is to only flash the 2MiB BIOS region. In that case it's
-not needed to extract blobs from vendor firmware and internal flashing is
-sufficient.
-* To flash the whole chip (e.g. to disable ME) blobs are needed to build
-coreboot. Blobs can be extracted with util/ifdtool from 4MiB full dump image
-(see below). Its recommended to include the VGA BIOS as well (4MiB write only).
-Kconfig is prepared already if it gets enabled (path and 8086,0102).
-```
-coreboot/3rdparty/blobs/mainboard/msi/ms7707
-├── descriptor.bin
-├── gbe.bin
-├── me.bin
-└── vgabios.bin
-```
-* Never write a full 4MiB image if blobs are not included. The generated
-coreboot.rom file is always 4MiB but the 2MiB flash command below will only
-flash the last 2MiB (BIOS) block.
-* The J1-Jumper sets the 'Flash Descriptor Override Strap-Pin' and enables
-full 4MiB access for internal flasher (read and write).
-* **Write BIOS-range** (2MiB) with J1-Jumper=off (as on picture/default
-	position):
-```
-flashrom -p internal:ich_spi_force=yes --noverify-all --ifd -i bios -w coreboot.rom
-```
-* **Read full dump** (4MiB) with J1-jumper=on:
-```
-flashrom -p internal -r original.rom
-```
-* **Write full dump** (4MiB) with J1-Jumper=on:
-```
-flashrom -p internal -w coreboot.rom
-```
-* After successful flashing turn main power off, wait some seconds to drain
-the capacitors, pull the battery and set the JBAT (clrcmos) jumper for some
-seconds. Setting the jumper alone is not enough (the Fintek is VBAT backed).
-Put all back in place and restart the board. It might need 1-2 AC power cycles
-to reinitialize (running at full fan speed - don't panic).
-* External flashing has been tested with RPi2 without main power connected.
-3.3V provided by RPi2. Read more about flashing methods [here](https://doc.coreboot.org/flash_tutorial/index.html).
-* In case of going back to proprietary BIOS create/save cmos settings as early
-as possible (do not leave BIOS on first start without saving settings).
-The BIOS might corrupt nvram (not cmos!) and leave the system in a dead state
-that needs an external flasher to revive. If stuck, reset the Fintek (see
-above) and restart the system several times and/or try setting J1 to
-temporarily disable ME.
-
-![](J1-flash-protect.jpg)
-
-* The JSPI1 header (5×2 2.0mm pitch pin header) for external flashing is
-directly connected to the flash chip. Additional 3.3V to /HOLD and /WP is not
-needed (internally re-routed already).

-### Internal programming
-
-The SPI flash can be accessed using [flashrom]. It is important to execute
-command with a `-c <chipname>` argument:
-
-    flashrom -p internal -c "MX25L1606E" -w coreboot.rom
-
-### External programming
-
-**IMPORTANT**: When programming SPI flash, first you need to enter apu1 in S5
-(Soft-off) power state. S5 state can be forced by shorting power button pin on
-J2 header.
-
-The external access to flash chip is available through standard SOP-8 clip or
-SOP-8 header next to the flash chip on the board. Notice that not all boards
-have a header soldered down originally. Hence, there could be an empty slot with
-8 eyelets, so you can solder down a header on your own. The SPI flash chip and
-SPI header are marked in the picture below. Also there is SPI header pin layout
-included. Notice, that signatures at the schematic can be ambiguous:
- J12 SPIDI = U35 SO = MISO
- J12 SPIDO = U35 SI = MOSI

-(\*) - It is used in normal SPI mode, but can be dangerous when using Quad SPI
-Flash. Then, pull-down resistors should be considered rather than jumper.
-
-### Internal programming
-
-The SPI flash can be accessed using [flashrom].
-
-    flashrom -p internal -w coreboot.rom
-
-### External programming
-
-**IMPORTANT**: When programming SPI flash, first you need to enter apu2 in S5
-(Soft-off) power state. S5 state can be forced by shorting power button pin on
-J2 header.
-
-The external access to flash chip is available through standard SOP-8 clip or
-SOP-8 header next to the flash chip on the board. Notice that not all boards
-have a header soldered down originally. Hence, there could be an empty slot with
-8 eyelets, so you can solder down a header on your own. The SPI flash chip and
-SPI header are marked in the picture below. Also there is SPI header and SPI
-flash pin layout included. Depend on using header or clip there are important
-rules:
- using header J6 - don't connect 1,7,8 pins
- using clip U23 - don't connect 3,7,8 pins
-
-Also signatures at the schematic can be ambiguous:
- J6 SPIDI = U23 SO = MISO
- J6 SPIDO = U23 SI = MOSI
-
-There is no restrictions as to the programmer device. It is only recommended to
-flash firmware without supplying power. External programming can be performed,
-for example using OrangePi and Armbian. You can exploit linux_spi driver which
-provides communication with SPI devices. Example command to program SPI flash
-with OrangePi using linux_spi:
-
-    flashrom -f -w coreboot.rom -p linux_spi:dev=/dev/spidev1.0,spispeed=16000

-This board currently requires:
-fsp blob	3rdparty/fsp/BraswellFspBinPkg/FspBin/BSWFSP.fd
-Microcode	Intel Braswell cpuid 1046C4 version 410
-		(Used pre-built binary retrieved from Intel site)
-
-## Flashing coreboot
-
-### Internal programming
-
-The main SPI flash can be accessed using [flashrom].
-
-### External programming
-
-The system has an internal flash chip which is a 8 MiB soldered SOIC-8 chip.
-This chip is located on the top middle side of the board. It's located
-between SoC and Q7 connector. Use clip (or solder wires) to program
-the chip.
-Specifically, it's a Winbond W25Q64FW (1.8V), whose datasheet can be found
-[here][W25Q64FW].
-
-## Known issues
-
- The PQ7 module contains Q7 connector only. Depending on the carrier
-serial/video/pcie ports might be available.
-
-## Untested
-
- hardware monitor
- SDIO
- Full Embedded Controller support
-
-## Working (using carrier)
-
- USB
- Gigabit Ethernet
- integrated graphics
- flashrom
- external graphics
- PCIe
- eMMC
- SATA
- serial port
- SMbus
- HDA (codec on carrier)
- initialization with FSP MR2
- SeaBIOS payload (version rel-1.11.0-44-g7961917)

-Roda RK9 Flash Header
-=====================
-
-There is a 5x2 pin, 1.27mm pitch header *J1* south of the BIOS flash. It
-follows the pinout of the Dediprog adaptor board:

-    | 9 10 |    9: GND     10: MOSI

-
-Pins 3 to 10 directly map to the regular SPI flash pinout.
-
-There is also a *JP17* around. Ideally, it should be closed during
-programming (isolates the SPI bus from the southbridge):

-In order to build coreboot, it's neccessary to extract some files from the vendor firmware. Make sure that you have a fully working dump.
-```bash
-[upsquared]$ ls
-firmware_vendor.rom
-```
-
-```bash
-[upsquared]$ mkdir extracted && cd extracted
-[extracted]$ ifdtool -x ../firmware_vendor.rom 
-File ../firmware_vendor.rom is 16777216 bytes

-flashregion_1_bios.bin
-flashregion_5_reserved.bin
-```
-
-### Clean up
-```bash
-[coreboot]$ make distclean
-```
-
-### Configuring
-```bash
-[coreboot]$ touch .config

-[coreboot]$ make olddefconfig
-```
-
-### Building
-```bash
-[coreboot]$ make
-```
-
-Now you should have a working and ready to use coreboot build at `build/coreboot.rom`.
-
-### Flashing
-```bash

-## SPD Addresses
-
-When porting a board from vendor firmware, the SPD addresses can be obtained
-through `i2c-tools`, which can be found in many GNU/Linux distributions. A more
-[detailed description](https://hannuhartikainen.fi/blog/hacking-ddr3-spd/) of
-the procedure and beyond can be found in
-[Hannu Hartikainen's blog](https://hannuhartikainen.fi).
-
-First load the kernel modules:
-
-```bash
-modprobe i2c-dev
-modprobe eeprom
-```
-
-Find the SMBus and the addresses of the DIMM's EEPROMs (example output):
-```bash
-$ decode-dimms | grep Decoding
-Decoding EEPROM: /sys/bus/i2c/drivers/eeprom/7-0050
-Decoding EEPROM: /sys/bus/i2c/drivers/eeprom/7-0052
-```
-
-Alternatively, look at the sys filesystem:
-```bash
-$ ls -l /sys/bus/i2c/drivers/eeprom/
-total 0
-lrwxrwxrwx 1 root root    0 Apr  4 01:46 6-0050 -> ../../../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/i2c-6/6-0050/
-lrwxrwxrwx 1 root root    0 Apr  4 01:46 7-0050 -> ../../../../devices/pci0000:00/0000:00:1f.3/i2c-7/7-0050/
-lrwxrwxrwx 1 root root    0 Apr  4 01:46 7-0052 -> ../../../../devices/pci0000:00/0000:00:1f.3/i2c-7/7-0052/

-lrwxrwxrwx 1 root root    0 Apr  4 01:47 module -> ../../../../module/eeprom/
--w------- 1 root root 4096 Apr  4 01:46 uevent
--w------- 1 root root 4096 Apr  4 01:47 unbind
-```
-
-The correct I2C bus is 7 in this case, and the EEPROMs are at `0x50` and `0x52`.
-Note that the above values are actually hex values.
-
-You can check the correctness of the SMBus and the addresses of the EEPROMs via
-`i2cdetect`:
-
-```bash
-$ i2cdetect -l
-i2c-3   unknown         i915 gmbus dpc                          N/A
-i2c-1   unknown         i915 gmbus vga                          N/A
-i2c-6   unknown         DPDDC-A                                 N/A
-i2c-4   unknown         i915 gmbus dpb                          N/A
-i2c-2   unknown         i915 gmbus panel                        N/A
-i2c-0   unknown         i915 gmbus ssc                          N/A
-i2c-7   unknown         SMBus I801 adapter at f040              N/A
-i2c-5   unknown         i915 gmbus dpd                          N/A
-```
-
-Probing the SMBus:
-
-```bash
-$ i2cdetect -r 7
-WARNING! This program can confuse your I2C bus, cause data loss and worse!
-I will probe file /dev/i2c-7 using receive byte commands.
-I will probe address range 0x03-0x77.

-The SPD addresses need to be left-shifted by 1 for `mrc.bin`, i.e., multiplied
-by 2. For example, if the addresses read through `i2c-tools` when booted from
-vendor firmware are `0x50` and `0x52`, the correct values would be `0xa0` and
-`0xa4`. This is because the I2C addresses are 7 bits long.

-# Intel Authenticated Code Modules
-
-The Authenticated Code Modules (ACMs) are Intel digitally signed modules
-that contain code to be run before the traditional x86 CPU reset vector.
-The ACMs can be invoked at runtime through the GETSEC instruction, too.
-
-A platform that wants to use Intel TXT must use two ACMs:
-1. BIOS ACM
-   * The BIOS ACM must be present in the boot flash.
-   * The BIOS ACM must be referenced by the [FIT].
-2. SINIT ACM
-   * The SINIT ACM isn't referenced by the [FIT].
-   * The SINIT ACM should be provided by the boot firmware, but bootloaders
-     like [TBOOT] are able to load them from the filesystem as well.
-
-## Retrieving ACMs
-
-The ACMs can be downloaded on Intel's website:
-[Intel Trusted Execution Technology](https://software.intel.com/en-us/articles/intel-trusted-execution-technology)
-
-If you want to extract the BLOB from vendor firmware you can search for the
-string ``LCP_POLICY_DATA`` or ``TXT``.
-
-## Header
-
-Every ACM has a fixed size header:
-
-```c
-/*
- * ACM Header v0.0 without dynamic part
- * Chapter A.1
- * Intel TXT Software Development Guide (Document: 315168-015)

-# Intel Trusted Execution Technology
-
-Intel TXT allows
-1. Attestation of the authenticity of a platform and its operating system.
-2. Assuring that an authentic operating system starts in a
-   trusted environment, which can then be considered trusted.
-3. Providing of a trusted operating system with additional
-   security capabilities not available to an unproven one.
-
-Intel TXT requirements:
-
-1. Intel TXT requires a **TPM** to measure parts of the firmware before it's
-   run on the BSP.
-2. Intel TXT requires signed **Authenticated Code Modules** ([ACM]s), provided
-   by Intel.
-3. Intel TXT requires **CPU and Chipset** support (supported since
-   Intel Core 2 Duo/ICH9).
-
-## Authenticated Code Modules
-
-The ACMs are Intel digitally signed modules that contain code to be run
-before the traditional x86 CPU reset vector.
-
-More details can be found here: [Intel ACM].
-
-## Modified bootflow with Intel TXT
-
-With Intel TXT the first instruction executed on the BSP isn't the
-*reset vector*, but the [Intel ACM].
-It initializes the TPM and measures parts of the firmware, the IBB.
-
-### Marking the Initial Boot Block
-
-Individual files in the CBFS can be marked as IBB.
-
-More details can be found in the [Intel TXT IBB] chapter.
-
-### Measurements
-The IBBs (Initial Boot Blocks) are measured into TPM's PCR0 by the BIOS [ACM]
-before the CPU reset vector is executed. To indentify the regions that need
-to be measured, the [FIT] contains one ore multiple *Type 7* entries, that
-point to the IBBs.
-
-### Authentication
-
-After the IBBs have been measured, the ACM decides if the boot firmware is
-trusted. There exists two validation modes:
-1. HASH Autopromotion
-   * Uses a known good HASH stored in TPM NVRAM
-   * Doesn't allow to boot a fallback IBB
-2. Signed BIOS policy
-   * Uses a signed policy stored in flash containing multiple HASHes
-   * The public key HASH of BIOS policy is burned into TPM by manufacturer
-   * Can be updated by firmware
-   * Allows to boot a fallback IBB
-
-At the moment only *Autopromotion mode* is implemented and tested well.
-
-In the next step the ACM terminates and the regular x86 CPU reset vector
-is being executed on the BSP.
-
-### Protecting Secrets in Memory
-
-Intel TXT sets the `Secrets in Memory` bit, whenever the launch of the SINIT
-ACM was successful.
-The bit is reset when leaving the *MLE* by a regular shutdown or by removing
-the CMOS battery.
-
-When `Secrets in Memory` bit is set and the IBB isn't trusted, the memory
-controller won't be unlocked, resulting in a platform that cannot access DRAM.
-
-When `Secrets in Memory` bit is set and the IBB is trusted, the memory
-controller will be unlocked, and it's the responsibility of the firmware to
-[clear all DRAM] and wipe any secrets of the MLE.
-The platform will be reset after all DRAM has been wiped and will boot
-with the `Secrets in Memory` bit cleared.
-
-### Configuring protected regions for SINIT ACM
-
-The memory regions used by the SINIT ACM need to be prepared and protected
-against DMA attacks.
-The SINIT ACM as well as the SINIT handoff data are placed in memory.
-
-### Locking TXT register
-
-As last step the TXT registers are locked.
-
-Whenever the SINIT ACM is invoked, it verifies that the hardware is in the
-correct state. If it's not the SINIT ACM will reset the platform.
-
-## For developers
-### Configuring Intel TXT in Kconfig
-Enable ``TEE_INTEL_TXT`` and set the following:
-
-``TEE_INTEL_TXT_BIOSACM_FILE`` to the path of the BIOS ACM provided by Intel
-
-``TEE_INTEL_TXT_SINITACM_FILE`` to the path of the SINIT ACM provided by Intel
-### Print TXT status as early as possible
-Add platform code to print the TXT status as early as possible, as the register
-is cleared on cold reset.

-# Intel TXT Initial Boot Block
-
-The Initial Boot Block (IBB) consists out of one or more files in the CBFS.
-
-## Constraints
-
-The IBB must follow the following constrains:
-* One IBB must contain the reset vector as well as the [FIT table].
-* The IBB should be as small as possible.
-* The IBBs must not overlap each other.
-* The IBB might overlap with microcode.
-* The IBB must not overlap the BIOS ACM.
-* The IBB size must be a multiple of 16.
-* Either one of the following:
-  * The IBB must be able to train the main system memory and clear all secrets.
-  * If the IBB cannot train the main system memory it must verify the code
-    that can train the main system memory and is able to clear all secrets.
-
-## Identification
-
-To add the IBBs to the [FIT], all CBFS files are added using the `cbfstool`
-with the `--ibb` flag set.
-The flags sets the CBFS file attribute tag to LE `' IBB'`.
-
-The make system in turn adds all those files to the [FIT] as type 7.
-
-## Intel TXT measurements
-
-Each IBB is measured and extended into PCR0 by [Intel TXT], before the CPU
-reset vector is executed.
-The IBBs are measured in the order they are listed in the [FIT].

-# Memory clearing
-
-The main memory on computer platforms in high security environments contains
-sensible data. On unexpected reboot the data might persist and could be
-read by a malicious application in the bootflow or userspace.
-
-In order to prevent leaking information from pre-reset, the boot firmware can
-clear the main system memory on boot, wiping all information.
-
-A common API indicates if the main memory has to be cleared. That could be
-on user request or by a Trusted Execution Environment indicating that secrets
-are in memory.
-
-As every platform has different bring-up mechanisms and memory-layouts, every
-The device must indicate support for memory clearing as part of the boot
-process.
-
-## Requirements
-
-1. The platform must clear all platform memory (DRAM) if requested
-2. Code that is placed in DRAM might be skipped (as workaround)
-3. Stack that is placed in DRAM might be skipped (as workaround)
-4. All DRAM is cleared with zeros
-
-## Implementation
-
-A platform that supports memory clearing selects Kconfig
-``PLATFORM_HAS_DRAM_CLEAR`` and calls
-
-```C
-bool security_clear_dram_request(void);
-```
-
-to detect if memory should be cleared.
-
-The memory is cleared in ramstage as part of `DEV_INIT` stage. It's possible to
-clear it earlier on some platforms, but on x86 MTRRs needs to be programmed
-first, which happens in `DEV_INIT`.
-
-Without MTRRs (and caches enabled) clearing memory takes multiple seconds.
-## Exceptions
-
-As some platforms place code and stack in DRAM (FSP1.0), the regions can be
-skipped.
-
-## Architecture specific implementations

-# vboot - Verified Boot Support
-
-Google's verified boot support consists of:
-
-*   A root of trust
-*   Special firmware layout
-*   Firmware verification
-*   Firmware measurements
-*   A firmware update mechanism
-*   Specific build flags
-*   Signing the coreboot image
-
-Google's vboot verifies the firmware and places measurements within the TPM.
-
-***
-
-## Root of Trust
-
-When using vboot, the root-of-trust is basically the read-only portion of the
-SPI flash. The following items factor into the trust equation:
-
-* The GCC compiler must reliably translate the code into machine code
-  without inserting any additional code (virus, backdoor, etc.)
-* The CPU must reliably execute the reset sequence and instructions as
-  documented by the CPU manufacturer.
-* The SPI flash must provide only the code programmed into it to the CPU
-  without providing any alternative reset vector or code sequence.
-* The SPI flash must honor the write-protect input and protect the specified
-  portion of the SPI flash from all erase and write accesses.
-
-The firmware is typically protected using the write-protect pin on the SPI
-flash part and setting some of the write-protect bits in the status register
-during manufacturing. The protected area is platform specific and for x86
-platforms is typically 1/4th of the SPI flash part size.
-Because this portion of the SPI flash is hardware write protected, it is not
-possible to update this portion of the SPI flash in the field, without altering
-the system to eliminate the ground connection to the SPI flash write-protect pin.
-Without hardware modifications, this portion of the SPI flash maintains the
-manufactured state during the system's lifetime.
-
-***
-
-## Firmware Layout
-
-Several sections are added to the firmware layout to support vboot:
-
-* Read-only section
-* Google Binary Blob (GBB) area
-* Read/write section A
-* Read/write section B
-
-The following sections describe the various portions of the flash layout.
-
-### Read-Only Section
-
-The read-only section contains a coreboot file system (CBFS) that contains all
-of the boot firmware necessary to perform recovery for the system. This firmware
-is typically protected using the write-protect pin on the SPI flash part and
-setting some of the write-protect bits in the status register during
-manufacturing.
-The protected area is typically 1/4th of the SPI flash part size and must cover
-the entire read-only section which consists of:
-
-* Vital Product Data (VPD) area
-* Firmware ID area
-* Google Binary Blob (GBB) area
-* coreboot file system containing read-only recovery firmware
-
-### Google Binary Blob (GBB) Area
-
-The GBB area is part of the read-only section. This area contains a 4096 or 8192
-bit public root RSA key that is used to verify the *VBLOCK* area to obtain the
-firmware signing key.
-
-### Recovery Firmware
-
-The recovery firmware is contained within a coreboot file system and consists of:
-
-* reset vector
-* bootblock
-* verstage
-* romstage
-* postcar
-* ramstage
-* payload
-* flash map file
-* config file
-* processor specific files:
-  * Microcode
-  * fspm.bin
-  * fsps.bin
-
-The recovery firmware is written during manufacturing and typically contains
-code to write the storage device (eMMC device or hard disk). The recovery image
-is usually contained on a socketed device such as a USB flash drive or an
-SD card. Depending upon the payload firmware doing the recovery, it may be
-possible for the user to interact with the system to specify the recovery
-image path. Part of the recovery is also to write the A and B areas of the SPI
-flash device to boot the system.
-
-### Read/Write Section
-
-The read/write sections contain an area which contains the firmware signing
-key and signature and an area containing a coreboot file system with a subset
-of the firmware. The firmware files in *FW_MAIN_A* and *FW_MAIN_B* are:
-
-* romstage
-* postcar
-* ramstage
-* payload
-* config file
-* processor specific files:
-  * Microcode
-  * fspm.bin
-  * fsps.bin
-
-The firmware subset enables most issues to be fixed in the field with firmware
-updates. The firmware files handle memory and most of silicon initialization.
-These files also produce the tables which get passed to the operating system.
-
-***
-
-## Firmware Updates
-
-The read/write sections exist in one of three states:
-
-* Invalid
-* Ready to boot
-* Successfully booted
-
-
-Firmware updates are handled by the operating system by writing any read/write
-section that is not in the "successfully booted" state. Upon the next reboot,
-vboot determines the section to boot. If it finds one in the "ready to boot"
-state then it attempts to boot using that section. If the boot fails then
-vboot marks the section as invalid and attempts to fall back to a read/write
-section in the "successfully booted" state. If vboot is not able to find a
-section in the "successfully booted" state then vboot enters recovery mode.
-
-Only the operating system is able to transition a section from the
-"ready to boot" state to the "successfully booted" state.
-The transition is typically done after the operating system has been running
-for a while indicating that successful boot was possible and the operating
-system is stable.
-
-Note that as long as the SPI write protection is in place then the system
-is always recoverable. If the flash update fails then the system will continue
-to boot using the previous read/write area. The same is true if coreboot passes
-control to the payload or the operating system and then the boot fails. In the
-worst case, the SPI flash gets totally corrupted in which case vboot fails the
-signature checks and enters recovery mode. There are no times where the SPI
-flash is exposed and the reset vector or part of the recovery firmware gets
-corrupted.
-
-***
-
-## Build Flags
-
-The following *Kconfig* values need to be selected to enable vboot:
-
-* COLLECT_TIMESTAMPS
-* VBOOT
-
-The starting stage needs to be specified by selecting either
-VBOOT_STARTS_IN_BOOTBLOCK or VBOOT_STARTS_IN_ROMSTAGE.
-
-If vboot starts in bootblock then vboot may be built as a separate stage by
-selecting `VBOOT_SEPARATE_VERSTAGE`. Additionally, if static RAM is too small
-to fit both verstage and romstage then selecting `VBOOT_RETURN_FROM_VERSTAGE`
-enables bootblock to reuse the RAM occupied by verstage for romstage.
-
-Non-volatile flash is needed for vboot operation. This flash area may be in
-CMOS, the EC, or in a read/write area of the SPI flash device.
-Select one of the following:
-
-* `VBOOT_VBNV_CMOS`
-* `VBOOT_VBNV_EC`
-* `VBOOT_VBNV_FLASH`
-
-More non-volatile storage features may be found in `security/vboot/Kconfig`.
-
-A TPM is also required for vboot operation.
-TPMs are available in `drivers/i2c/tpm` and `drivers/pc80/tpm`.
-
-In addition to adding the coreboot files into the read-only region,
-enabling vboot causes the build script to add the read/write files into
-coreboot file systems in *FW_MAIN_A* and *FW_MAIN_B*.
-
-***
-
-## Signing the coreboot Image
-
-The following command script is an example of how to sign the coreboot image
-file. This script is used on the Intel Galileo board and creates the *GBB* area
-and inserts it into the coreboot image. It also updates the *VBLOCK* areas with
-the firmware signing key and the signature for the *FW_MAIN* firmware.
-More details are available in `3rdparty/vboot/README`.

-## Boot Flow
-
-The reset vector exist in the read-only area and points to the bootblock
-entry point. The only copy of the bootblock exists in the read-only area
-of the SPI flash. Verstage may be part of the bootblock or a separate stage.
-If separate then the bootblock loads verstage from the read-only area and
-transfers control to it.
-
-Upon first boot, verstage attempts to verify the read/write section A.
-It gets the public root key from the GBB area and uses that to verify the
-*VBLOCK* area in read-write section A. If the *VBLOCK* area is valid then it
-extracts the firmware signing key (1024-8192 bits) and uses that to verify
-the *FW_MAIN_A* area of read/write section A. If the verification is successful
-then verstage instructs coreboot to use the coreboot file system in read/write
-section A for the contents of the remaining boot firmware (romstage, postcar,
-ramstage and the payload).
-
-If verification fails for the read/write area and the other read/write area is
-not valid vboot falls back to the read-only area to boot into system recovery.

-## Chromebook Special Features
-
-Google's Chromebooks have some special features:
-
-* Developer mode
-* Write-protect screw
-
-### Developer Mode
-
-Developer mode allows the user to use coreboot to boot another operating system.
-This may be a another (beta) version of Chrome OS, or another flavor of
-GNU/Linux. Use of developer mode does not void the system warranty. Upon entry
-into developer mode, all locally saved data on the system is lost.
-This prevents someone from entering developer mode to subvert the system
-security to access files on the local system or cloud.
-
-### Write Protect Screw
-
-Chromebooks have a write-protect screw which provides the ground to the
-write-protect pin of the SPI flash.
-Google specifically did this to allow the manufacturing line and advanced
-developers to re-write the entire SPI flash part. Once the screw is removed,
-any firmware may be placed on the device.
-However, accessing this screw requires opening the case and voids the
-system warranty!

-# AMD Family 17h in coreboot
-
-## Abstract
-
-Beginning with Family 17h products (a.k.a. “Zen” cores), AMD
-changed their paradigm for initializing the system and this requires
-major modifications to the execution flow of coreboot.  This file
-discusses the new boot flow, and challenges, and the tradeoffs of the
-initial port into coreboot.
-
-## Introduction
-
-Family 17h products are x86-based designs.  This documentation assumes
-familiarity with x86, its reset state and its early initialization
-requirements.
-
-To the extent necessary, the role of the Platform Security Processor
-(a.k.a. PSP) in system initialization is addressed here.  AMD has
-historically required an NDA for access to the PSP
-specification<sup>1</sup>.  coreboot relies on util/amdfwtool to build
-the structures and add various other firmware to the final image.  The
-Family 17h PSP design guide adds a new BIOS Directory Table, similar to
-the PSP Directory Table.
-
-Support in coreboot for modern AMD products is based on AMD’s
-reference code:  AMD Generic Encapsulated Software Architecture
-(AGESA<sup>TM</sup>).  AGESA contains the technology for enabling DRAM,
-configuring proprietary core logic, assistance with generating ACPI
-tables, and other features.
-
-AGESA for products earlier than Family 17h is known as v5 or
-Arch2008<sup>2</sup>.  Also note that coreboot currently contains both
-open source AGESA and closed source implementations (binaryPI) compiled
-from AGESA.
-
-The first AMD Family 17h device ported to coreboot is codenamed
-“Picasso”<sup>3</sup>, and will be added to soc/amd/picasso.
-
-## Additional Definitions
-
-*   PSP, Platform Security Processor:  Onboard ARM processor that runs
-alongside the main x86 processor; may be viewed as analogous to the
-Intel<sup>R</sup> Management Engine
-*   FCH, Fusion Control Hub, the logical southbridge within the SOC
-*   ABL - AGESA Bootloader - Processor initialization code that runs on
-the PSP
-*   PSP Directory Table - A structured list of pointers to PSP firmware
-and other controller binaries
-*   BIOS Directory Table - A structured list of pointers to BIOS
-related firmware images
-*   Embedded Firmware Structure - Signature and pointers used by the
-PSP to locate the PSP Directory Table and BIOS Directory Table; these
-items are generated during coreboot build and are located in the SPI ROM
-*   Verstage - The code to verify the firmware contained in the
-writable section of the SPI ROM
-*   APCB - AMD PSP Customization Block - A binary containing PSP and
-system configuration preferences (analogous to v5 BUILDOPT_ options),
-and generated by APCBTool to be added to coreboot/utils later
-*   APOB - AGESA PSP Output Buffer - A buffer in main memory for
-storing AGESA BootLoader output.  There are no plans for this to be
-parsed by coreboot
-
-## Problem Statements
-
-AMD has ported early AGESA features to the PSP, which now discovers,
-enables and trains DRAM.  Unlike any other x86 device in coreboot, a
-Picasso system has DRAM online prior to the first instruction fetch.
-
-Cache-as-RAM (CAR) is no longer a supportable feature in AMD hardware.
-Early code expecting CAR behavior <span
-style="text-decoration:underline;">must</span> account for writes
-escaping the L2 cache and going to DRAM.
-
-Without any practical need for CAR, or DRAM initialization, coreboot
-should arguably skip bootblock and romstage, and possibly use ramstage
-as the BIOS image.  This approach presents a number of challenges:
-
-*   At the entry of ramstage, x86 processors are in flat protected
-mode.  Picasso’s initial state is nearly identical to any other x86
-at reset, except its CS shadow register’s base and limit put its
-execution within DRAM, not at 0xfffffff0.  Picasso requires initial
-programming and entry into protected mode prior to ramstage.
-*   coreboot expects cbmem initialization during romstage.
-
-AGESA supporting Picasso is now at v9.  Unlike Arch2008, which defines
-granular entry points for easy inclusion to a legacy BIOS, v9 is
-rewritten for compilation into a UEFI.  The source follows UEFI
-standards, i.e. assumes the presence of UEFI phases, implements
-dependency expressions, much functionality is rewritten as libraries,
-etc.  It would, in no way, fit into the v5 model used in coreboot.
-
-*   For the foreseeable future, AGESA source will distributed only
-under NDA.
-
-## Basic Pre-x86 Boot Flow
-
-The following steps occur prior to x86 processor operation.
-
-*   System power on
-*   PSP executes immutable on-chip boot ROM
-*   PSP locates the Embedded Firmware Table and PSP Directory Table in

-to the flash device.
-    *   Verstage verifies the RW sections (as is typically performed by
-the main processor)
-    *   Verstage locates the Embedded Firmware Directory within the
-verified FMAP section and passes a pointer to the PSP bootloader.  If
-the verification fails, it passes a pointer to the RO header to the
-bootloader.
-*   PSP parses the PSP Directory Table to find the ABLs and executes

-## Picasso Reset Vector and First Instructions
-
-As mentioned above, prior to releasing the x86 main core from reset,
-the PSP decompresses a BIOS image into DRAM.  The PSP uses a specific
-BIOS Directory Table entry type to determine the source address (in
-flash), the destination address (in DRAM), and the destination size.
-The decompressed image is at the top of the destination region.  The
-PSP then
-
-Calculates the x86 reset vector as
-
-    reset_vector	= dest_addr + dest_size - 0x10
-
-Sets x86 CS descriptor shadow register to
-
-    base		= dest_addr + dest_size - 0x10000
-    limit		= 0xffff
-
-Like all x86 devices, the main core is allowed to begin executing
-instructions with
-
-    CS:IP		= 0xf000:0xfff0
-
-For example, assume the BIOS Directory Table indicates
-
-    destination	= 0x9b00000
-    size		= 0x300000
-
-… then the BIOS image is placed at the topmost position the region
-0x9b00000-0x9dfffff and
-
-    reset_vector	= 0x9dffff0
-    CS_shdw_base	= 0x9df0000
-    CS:IP		= 0xf000:0xfff0
-
-Although the x86 behaves as though it began executing at 0xfffffff0
-i.e. 0xf000:0xfff0, the initial GDT load must use the physical address
-of the table and not the typical CS-centric address.  And, the first
-jump to protected mode must jump to the physical address in DRAM.  Any
-code that is position-dependent must be linked to run at the final
-destination.
-
-## Initial coreboot Implementation
-
-Supporting Picasso doesn’t fit well with many of the coreboot
-assumptions.  Initial porting shall attempt to fit within existing
-coreboot paradigms and make minimal changes to common code.
-
-### CAR and bootblock
-
-The coreboot bootblock contains features Picasso doesn’t require or
-can’t use, and is assumed to execute in an unusable location.
-Picasso’s requirement for bootblock in coreboot will be eliminated.
-
-### Hybrid romstage
-
-Picasso’s x86 reset state doesn’t meet the coreboot expectations
-for jumping directly to ramstage.  The primary feature of romstage is
-also not needed, however there are other important features that are
-typically in romstage that Picasso does need.
-
-The romstage architecture is designed around the presence of CAR.
-Several features implement ROMSTAGE_CBMEM_INIT_HOOK, expecting to move
-data from CAR to cbmem.  The hybrid romstage consumes DRAM for the
-purpose of implementing the expected CAR storage.  This region as well
-as the DRAM where romstage is decompressed must be reserved and
-unavailable to the OS.
-
-The initial Picasso port implements a hybrid romstage that contains the
-first instruction fetched at the reset vector.  It minimally configures
-flat protected mode, initializes cbmem, then loads the next stage.
-Future work will consider breaking the dependencies mentioned above
-and/or potentially loading ramstage directly from the PSP.
-
-## AGESA v9 on Picasso
-
-Due to the current inability to publish AGESA source, a pre-built
-binary solution remains a requirement.  The rewrite from v5 to v9 for
-direct inclusion into UEFI source makes modifying it for conforming to
-the existing v5 interface impractical.
-
-Given the UEFI nature of modern AGESA, and the existing open source
-work from Intel, Picasso shall support AGESA via an FSP-like prebuilt
-image.  The Intel Firmware Support Package<sup>4</sup> combines
-reference code with EDK II source to create a modular image with
-discoverable entry points.  coreboot source already contains knowledge
-of FSP, how to parse it, integrate it, and how to communicate with it.

-# Apollolake
-## SPI flash layout
-
-![][apl_flash_layout]
-
-With Apollolake Intel invented another flash layout for x86 firmware called IFWI (Intel FirmWare Image).
-
-Usually on x86 platforms the bootblock is stored at the end of the bios region
-and the Intel ME / TXE has its own IFD region. On Apollolake both have been
-moved into the IFWI region, which is a subregion of "BIOS", since it allows to
-store multiple firmware components.
-
-The IFWI region can be manipulated by `ifwitool`.

-# Intel Firmware Interface Table
-
-The FIT allows to run code before the actual IA32 reset vector is executed
-by the CPU. The FIT resides in the BIOS region (usually near the reset vector)
-and is pointed to by the FIT pointer residing at `0xFFFFFFC0`.
-
-## Table layout
-The table consists of blocks each 16 bytes in size.
-The first is called *FIT header* the other are called *FIT entry*.

-# Intel Firmware Support Package (FSP)-specific documentation
-
-This section contains documentation about Intel-FSP in public domain.
-
-## Bugs
-As Intel doesn't even list known bugs, they are collected here until
-those are fixed. If possible a workaround is described here as well.
-
-### BroadwellDEFsp
-
-* IA32_FEATURE_CONTROL MSR is locked in FSP-M
-  * Release MR2
-  * Writing the MSR is required in ramstage for Intel TXT
-  * Workaround: none
-  * Issue on public tracker: [Issue 10]
-
-* FSP-S asserts if the thermal PCI device 00:1f.6 is disabled
-  * Release MR2
-  * FSP expects the PCI device to be enabled
-  * FSP expects BARs to be properly assigned
-  * Workaround: Don't disable this PCI device
-  * Issue on public tracker: [Issue 13]
-
-### KabylakeFsp
-* MfgId and ModulePartNum in the DIMM_INFO struct are empty
-  * Release 3.7.1
-  * Those values are typically consumed by SMBIOS type 17
-  * Workaround: none
-  * Issue on public tracker: [Issue 22]
-
-### BraswellFsp
-* Internal UART can't be disabled using PcdEnableHsuart*
-  * Release MR2

-# PEIM to PEIM Interface (PPI)
-
-This section is intended to document the purpose of creating PPI service
-inside coreboot space to perform some specific operation related to CPU,
-chipset using Intel FSP. This feature is added into FSP specification 2.1
-where FSP should be able to locate PPI, published by boot firmware and
-able to execute the same in FSP's context.
