mb/system76/gaze16: 3060: Add variant for I219-V GbE

Some models use Intel I219-V instead of the Realtek RTL8111 controller.
Introduce a new variant so the IFD of the Realtek board does not have
the onboard LAN enabled when it is not connected.

+</ol>
+
+<h3>Building QuarkFspPkg</h3>
+<p>
+There are two versions of FSP: FSP 1.1 and FSP 2.0.  There are also two
+different implementations of FSP, one using subroutines without SEC and
+PEI core and the original implementation which relies on SEC and PEI core.
+Finally there are two different build x86 types release (r32) and debug (d32).
+</p>
+<p>Note that the subroutine implementations are a <b>work in progress</b>.</p>
+<p>
+Build commands shown building debug FSP:
+</p>
+<ul>
+  <li>Linux:
+    <ul>
+      <li>QuarkFspPkg/BuildFsp1_1.sh  -d32</li>
+      <li>QuarkFspPkg/BuildFsp1_1Pei.sh  -d32</li>

+      <li>Windows: QuarkFspPkg/BuildFsp2_0.bat  -d32</li>
+    </ul>
+  </li>
+</ul>
+
+<h3>Copying FSP files into coreboot Source Tree</h3>
+<p>
+There are some helper scripts to copy the FSP output into the coreboot
+source tree.  The parameters to these scripts are:
+</p>
+<ol>
+  <li>EDK2 tree root</li>
+  <li>coreboot tree root</li>

+<h3>Intel Firmware Descriptor</h3>
+<p>
+  The Intel Firmware Descriptor (IFD) is located at the base of the flash part.
+  The following command overwrites the base of the flash image with the Intel
+  Firmware Descriptor:
+</p>
+<pre><code>dd if=descriptor.bin of=build/coreboot.rom conv=notrunc >/dev/null 2>&1</code></pre>

+  call dev_* routines which use the tables in static.c to locate operation tables
+  associated with the various chips and devices.  After location the operation
+  tables, the state routines call one or more functions depending upon the
+  state of the state machine.
+</p>
+
+<h4><a name="ChipOperations">Chip Operations</a></h4>
+<p>
+  Kick-starting the ramstage state machine requires creating the operation table
+  for the chip listed in devicetree.cb:

+      </li>
+      <li>Use the CHIP_NAME macro to specify the name for the chip</li>

+
+<h4>Domain Operations</h4>
+<p>
+  coreboot uses the domain operation table to initiate operations on all of the
+  devices in the domain.  By default coreboot enables all PCI devices which it
+  finds.  Listing a device in devicetree.cb gives the board vendor control over
+  the device state.  Non-PCI devices may also be listed under PCI device such as
+  the LPC bus or SMbus devices.
+</p>
+<ol>
+  <li>Edit src/soc/&lt;SoC Vendor&gt;/&lt;SoC Family&gt;/chip.c:
+    <ol type="A">
+      <li>
+        The domain operation table is typically placed in
+        src/soc/&lt;SoC Vendor&gt;/&lt;SoC Family&gt;/chip.c.
+        The table typically looks like the following:
+<pre><code>static struct device_operations pci_domain_ops = {
+	.read_resources	= pci_domain_read_resources,
+	.set_resources	= pci_domain_set_resources,
+	.scan_bus	= pci_domain_scan_bus,
+};
+</code></pre>
+      </li>
+      <li>
+        Create a .enable_dev entry in the chip operations table which points to a
+        routine which sets the domain table for the device with the DEVICE_PATH_DOMAIN.
+<pre><code>	if (dev->path.type == DEVICE_PATH_DOMAIN) {
+		dev->ops = &pci_domain_ops;
+	}
+</code></pre>
+      </li>
+      <li>
+        During the BS_DEV_ENUMERATE state, ramstage now display the device IDs

+  </li>
+</ol>
+
+
+<h3><a name="DeviceDrivers">PCI Device Drivers</a></h3>
+<p>
+  PCI device drivers consist of a ".c" file which contains a "pci_driver" data
+  structure at the end of the file with the attribute tag "__pci_driver".  This
+  attribute tag places an entry into a link time table listing the various
+  coreboot device drivers.

+<h4><a name="SubsystemIds">Subsystem IDs</a></h4>
+<p>
+  PCI subsystem IDs are assigned during the BS_DEV_ENABLE state.  The device
+  driver may use the common mechanism to assign subsystem IDs by adding
+  the ".ops_pci" to the pci_driver data structure.  This field points to
+  a "struct pci_operations" that specifies a routine to set the subsystem
+  IDs for the device.  The routine might look something like this:
+</p>
+<pre><code>static void pci_set_subsystem(struct device *dev, unsigned vendor, unsigned device)
+{
+	if (!vendor || !device) {
+		vendor = pci_read_config32(dev, PCI_VENDOR_ID);
+		device = vendor >> 16;
+	}
+	printk(BIOS_SPEW,
+		"PCI: %02x:%02x:%d subsystem vendor: 0x%04x, device: 0x%04x\n",
+		0, PCI_SLOT(dev->path.pci.devfn), PCI_FUNC(dev->path.pci.devfn),
+		vendor & 0xffff, device);
+	pci_write_config32(dev, PCI_SUBSYSTEM_VENDOR_ID,
+			((device & 0xffff) << 16) | (vendor & 0xffff));
+}
+</code></pre>
+
+
+
+<h3>Set up the <a name="MemoryMap">Memory Map</a></h3>
+<p>
+  The memory map is built by the various PCI device drivers during the
+  BS_DEV_RESOURCES state of ramstage.  The northcluster driver will typically
+  specify the DRAM resources while the other drivers will typically specify
+  the IO resources.  These resources are hung off the struct device *data structure by
+  src/device/device_util.c/<a target="_blank" href="https://review.coreboot.org/gitweb?p=coreboot.git;a=blob;f=src/device/device_util.c;hb=HEAD#l448">new_resource</a>.
+</p>
+<p>
+  During the BS_WRITE_TABLES state, coreboot collects these resources and
+  places them into a data structure identified by LB_MEM_TABLE.
+</p>
+<p>
+  Edit the device driver file:
+</p>
+<ol>
+  <li>
+    Implement a read_resources routine which calls macros defined in
+    src/include/device/<a target="_blank" href="https://review.coreboot.org/gitweb?p=coreboot.git;a=blob;f=src/include/device/device.h;hb=HEAD#l237">device.h</a>
+    like:
+    <ul>
+      <li>ram_resource</li>
+      <li>reserved_ram_resource</li>
+      <li>bad_ram_resource</li>
+      <li>uma_resource</li>
+      <li>mmio_resource</li>
+    </ul>
+  </li>
+</ol>
+
+<p>
+  Testing: Verify that the resources are properly displayed by coreboot during the BS_WRITE_TABLES state.

-# Background
-
-CB:31250 ("soc/intel/cannonlake: Configure GPIOs again after FSP-S is
-done") introduced a workaround in coreboot for `soc/intel/cannonlake`
-platforms to save and restore GPIO configuration performed by
-mainboard across call to FSP Silicon Init (FSP-S). This workaround was
-required because FSP-S was configuring GPIOs differently than
-mainboard resulting in boot and runtime issues because of
-misconfigured GPIOs. This issue was observed on `google/hatch`
-mainboard and was raised with Intel to get the FSP behavior
-fixed. Until the fix in FSP was available, this workaround was used to
-ensure that the mainboards can operate correctly and were not impacted
-by the GPIO misconfiguration in FSP-S.
-
-The issues observed on `google/hatch` mainboard were fixed by adding
-(if required) and initializing appropriate FSP UPDs. This UPD
-initialization ensured that FSP did not configure any GPIOs
-differently than the mainboard configuration. Fixes included:
- * CB:31375 ("soc/intel/cannonlake: Configure serial debug uart")
- * CB:31520 ("soc/intel/cannonlake: Assign FSP UPDs for HPD and Data/CLK of DDI ports")
- * CB:32176 ("mb/google/hatch: Update GPIO settings for SD card and SPI1 Chip select")
- * CB:34900 ("soc/intel/cnl: Add provision to configure SD controller write protect pin")
-
-With the above changes merged, it was verified on `google/hatch`
-mainboard that the workaround for GPIO reconfiguration was not
-needed. However, at the time, we missed dropping the workaround in
-'soc/intel/cannonlake`. Currently, this workaround is used by the
-following mainboards:
- * `google/drallion`
- * `google/sarien`
- * `purism/librem_cnl`
- * `system76/lemp9`
-
-As verified on `google/hatch`, FSP v1263 included all UPD additions
-that were required for addressing this issue.
-
-# Proposal
-
-* The workaround can be safely dropped from `soc/intel/cannonlake`
-  only after the above mainboards have verified that FSP-S does not
-  configure any pads differently than the mainboard in coreboot. Since
-  the fix included initialization of FSP UPDs correctly, the above
-  mainboards can use the following diff to check what pads change
-  after FSP-S has run:

-* The fix implemented in FSP/coreboot for `soc/intel/cannonlake`
-  platforms is not really the right long term solution for the
-  problem. Ideally, FSP should not be touching any GPIO configuration
-  and letting coreboot configure the pads as per mainboard
-  design. This recommendation was accepted and implemented by Intel
-  starting with Jasper Lake and Tiger Lake platforms using a single
-  UPD `GpioOverride` that coreboot can set so that FSP does not change
-  any GPIO configuration. However, this implementation is not
-  backported to any older platforms. Given the issues that we have
-  observed across different platforms, the second proposal is to:
-
-  - Add a Kconfig `CHECK_GPIO_CONFIG_CHANGES` that enables checks
-    in coreboot to stash GPIO pad configuration before various calls
-    to FSP and compares the configuration on return from FSP.
-  - This will have to be implemented as part of
-    drivers/intel/fsp/fsp2_0/ to check for the above config selection
-    and make callbacks `gpio_snapshot()` and `gpio_verify_snapshot()`
-    to identify and print information about pads that have changed
-    configuration after calls to FSP.
-  - This config can be kept disabled by default and mainboard
-    developers can enable them as and when required for debug.
-  - This will be helpful not just for the `soc/intel/cannonlake`
-    platforms that want to get rid of the above workaround, but also
-    for all future platforms using FSP to identify and catch any GPIO
-    misconfigurations that might slip in to any platforms (in case the
-    `GpioOverride` UPD is not honored by any code path within FSP).

-### Naming and referencing devices
-
-When declaring a device, it can optionally be given an alias that can be
-referred to elsewhere. This is particularly useful to declare a device in one
-device tree while allowing its configuration to be more easily changed in an
-overlay. For instance, the AMD Picasso SoC definition
-(`soc/amd/picasso/chipset.cb`) declares an IOMMU on a PCI bus that is disabled
-by default:
-
-```
-chip soc/amd/picasso
-	device domain 0 on
-		...
-		device pci 00.2 alias iommu off end
-		...
-	end
-end
-```
-
-A device based on this SoC can override the configuration for the IOMMU without
-duplicating addresses, as in
-`mainboard/google/zork/variants/baseboard/devicetree_trembyle.cb`:
-
-```
-chip soc/amd/picasso
-	device domain 0
-		...
-		device ref iommu on end
-		...
-	end
-end
-```
-
-In this example the override simply enables the IOMMU, but it could also
-set additional properties (or even add child devices) inside the IOMMU `device`
-block.
-
----
-
-It is important to note that devices that use `device ref` syntax to override
-previous definitions of a device by alias must be placed at **exactly the same
-location in the device tree** as the original declaration. If not, this will
-actually create another device rather than overriding the properties of the
-existing one. For instance, if the above snippet from `devicetree_trembyle.cb`
-were written as follows:
-
-```
-chip soc/amd/picasso
-	# NOTE: not inside domain 0!
-	device ref iommu on end
-end
-```
-
-Then this would leave the SoC's IOMMU disabled, and instead create a new device
-with no properties as a direct child of the SoC.

-.c files should keep all C code wrapped in `#ifndef __ASSEMBLER__` blocks,
-including includes to other headers that don't follow that provision. Where a
-specific include order is required for technical reasons, it should be clearly
-documented with comments.
-
-Files should generally include every header they need a definition from
-directly (and not include any unnecessary extra headers). Excepted from
-this are certain headers that intentionally chain-include other headers
-which logically belong to them and are just factored out into a separate
-location for implementation or organizatory reasons. This could be
-because part of the definitions is generic and part SoC-specific (e.g.
-`<gpio.h>` chain-including `<soc/gpio.h>`), architecture-specific (e.g.
-`<device/mmio.h>` chain-including `<arch/mmio.h>`), separated out into
-commonlib[/bsd] for sharing/license reasons (e.g. `<cbfs.h>`
-chain-including `<commonlib/bsd/cbfs_serialized.h>`) or just split out
-to make organizing subunits of a larger header easier. This can also
-happen when certain definitions need to be in a specific header for
-legacy POSIX reasons but we would like to logically group them together
-(e.g. `uintptr_t` is in `<stdint.h>` and `size_t` in `<stddef.h>`, but
-it's nicer to be able to just include `<types.h>` and get all the common
-type and helper function stuff we need everywhere).
-
-The headers `<kconfig.h>`, `<rules.h>` and `<commonlib/bsd/compiler.h>`
-are always automatically included in all compilation units by the build
-system and should not be included manually.

-GCC extensions
---------------
-
-GCC is the only officially-supported compiler for coreboot, and a
-variety of its C language extensions are heavily used throughout the
-code base. There have been occasional attempts to add clang as a second
-compiler option, which is generally compatible to the same language
-extensions that have been long-established by GCC.
-
-Some GCC extensions (e.g. inline assembly) are basically required for
-proper firmware development. Others enable more safe or flexible
-coding patterns than can be expressed with standard C (e.g. statement
-expressions and `typeof()` to avoid double evaluation in macros like
-`MAX()`). Yet others just add some simple convenience and reduce
-boilerplate (e.g. `void *` arithmetic).
-
-Since some GCC extensions are necessary either way, there is no gain
-from avoiding other GCC extensions elsewhere. The use of all official
-GCC extensions is expressly allowed within coreboot. In cases where an
-extension can be replaced by a 100% equivalent C standard feature with
-no extra boilerplate or loss of readability, the C standard feature
-should be preferred (this usually only happens when GCC retains an
-older pre-standardization extension for backwards compatibility, e.g.
-the old pre-C99 syntax for designated initializers). But if there is
-any advantage offered by the GCC extension (e.g. using GCC zero-length
-arrays instead of C99 variable-length arrays because they don't inhibit
-`sizeof()`), there is no reason to deprive ourselves of that, and "this
-is not C standard compliant" should not be a reason to argue against
-its use in reviews.
-
-This rule only applies to explicit GCC extensions listed in the
-"Extensions to the C Language Family" section of the GCC manual. Code
-should never rely on incidental GCC translation behavior that is not
-explicitly documented as a feature and could change at any moment.

-
-  * coreboot offers you the opportunity to work with various architectures
-    right on the iron. coreboot supports both current and older silicon for a
-    wide variety of chips and technologies.
-
-  * coreboot has a worldwide developer and user base.
-
-  * We are a very passionate team, so you will interact directly with the
-    project initiators and project leaders.
-
-  * We have a large, helpful community. coreboot has some extremely talented
-    and helpful experts in firmware involved in the project. They are ready to
-    assist and mentor contributors participating in GSoC.
-
-  * One of the last areas where open source software is not common is firmware.
-    Running proprietary firmware can have severe effects on user's freedom and
-    security. coreboot has a mission to change that by providing a common
-    framework for initial hardware initialization and you can help us succeed.

-## Contributor requirements & commitments
-
-Google Summer of Code is a significant time commitment for you. Medium-sized
-projects are estimated to take 175 hours, while large-sized projects are
-estimated to take 350 hours. Depending on the project size, this means we
-expect you to work roughly half-time or full-time on your project during the
-three months of coding. We expect to be able to see this level of effort in the
-results.
-
-The standard program duration is 12 weeks and in consultation with the mentor
-it can be extended up to 22 weeks. Please keep in mind that the actual number
-of hours you spend on the project highly depends on your skills and previous
-experience.
-
-Make sure that your schedule (exams, courses, day job) gives you a sufficient
-amount of spare time. If this is not the case, then you should not apply.
-
-
-### Before applying
-
-  * Join the [mailing list] and our other [community forums]. Introduce yourself
-    and mention that you are a prospective GSoC contributor. Ask questions and
-    discuss the project that you are considering. Community involvement is a
-    key component of coreboot development.
-
-  * You accept our [Code of Conduct] and [Language style].
-
-  * Demonstrate that you can work with the coreboot codebase.
-
-    * Look over some of the development processes guidelines: [Getting started],
-      [Tutorial], [Flashing firmware tutorial] and [Coding style].
-
-    * Download, build and boot coreboot in QEMU or on real hardware. Please email
-      your serial output results to the [mailing list].
-
-    * Look through some patches on Gerrit to get an understanding of the review
-      process and common issues.
-
-    * Get signed up for Gerrit and push at least one patch to Gerrit for review.
-      Check the [easy project list][Project ideas] or ask for simple tasks on
-      the [mailing list] or on our other [community forums] if you need ideas.
-
-
-### During the program
-
-  * To pass and to be paid by Google requires that you meet certain milestones.
-
-    * First, you must be in good standing with the community before the official
-      start of the program. We expect you to post some design emails to the
-      [mailing list], and get feedback on them, both before applying, and during
-      the "community bonding period" between acceptance and official start.
-
-    * You must have made progress and committed significant code before the
-      mid-term point and by the final.
-
-    * We require that accepted contributors to maintain a blog, where you are
-      expected to write about your project *WEEKLY*. This is a way to measure
-      progress and for the community at large to be able to help you. GSoC is
-      *NOT* a private contract between your mentor and you.
-
-  * You must be active in the community on IRC and the [mailing list].
-
-  * You are expected to work on development publicly, and to push commits to the
-    project on a regular basis. Depending on the project and what your mentor
-    agrees to, these can be published directly to the project or to a public
-    repository such as Gitlab or Github. If you are not publishing directly to
-    the project codebase, be aware that we do not want large dumps of code that
-    need to be rushed to meet the mid-term and final goals.
-
-We don't expect our contributors to be experts in our problem domain, but we
-don't want you to fail because some basic misunderstanding was in your way of
-completing the task.
-
-
-## Projects
-
-There are many development tasks available in coreboot. We prepared some ideas
-for Summer of Code projects. These are projects that we think can be managed in
-the timeline of GSoC, and they cover areas where coreboot is trying to reach
-new users and new use cases.
-
-Of course your application does not have to be based on any of the ideas listed.
-It is entirely possible that you have a great idea that we just didn't think of
-yet. Please let us know!
-
-The blog posts related to previous GSoC projects might give some insights to
-what it is like to be a coreboot GSoC contributor.
-
-
-## coreboot Summer of Code Application
-
-coreboot welcomes contributors from all backgrounds and levels of experience.
-
-Your application should include a complete project proposal. You should
-document that you have the knowledge and the ability to complete your proposed
-project. This may require a little research and understanding of coreboot prior
-to sending your application. The community and coreboot project mentors are your
-best resource in fleshing out your project ideas and helping with a project
-timeline. We recommend that you get feedback and recommendations on your
-proposal before the application deadline.
-
-Please complete the standard GSoC application and project proposal. Provide the
-following information as part of your application. Make sure to provide multiple
-ways of communicating in case your equipment (such as a laptop) is lost,
-damaged, or stolen, or in case of a natural disaster that disrupts internet
-service. You risk automatically failing if your mentor cannot contact you and if
-you cannot provide updates according to GSoC deadlines.

-## Mentors
-
-Each accepted project will have at least one mentor. We will match mentors and
-contributors based on the project and experience level. If possible, we also
-will try to match their time zones.
-
-Mentors are expected to stay in frequent contact with the contributor and
-provide guidance such as code reviews, pointers to useful documentation, etc.
-This should generally be a time commitment of several hours per week.
-
-Some projects might have more than one mentor, who can serve as a backup. They
-are expected to coordinate with each other and a contributor on a regular basis,
-and keep track of the contributor process. They should be able to take over
-mentoring duty if one of the mentors is unavailable (vacations, sickness,
-emergencies).
-
-
-### Volunteering to be a mentor
-
-If you'd like to volunteer to be a mentor, please read the [GSoC Mentor Guide].
-This will give you a better idea of expectations, and where to go for help.
-After that, contact Org Admins (see coreboot contacts section above).
-
-The following coreboot developers have volunteered to be GSoC 2022 mentors.
-Please stop by in our community forums and say hi to them and ask them
-questions.

+## Add Kernel Address Sanitizer functionality to coreboot
+The Kernel Address Sanitizer (KASAN) is a runtime dynamic memory error detector.
+The idea is to check every memory access (variables) for its validity
+during runtime and find bugs like stack overflow or out-of-bounds accesses.
+Implementing this stub into coreboot like "Undefined behavior sanitizer support"
+would help to ensure code quality and make the runtime code more robust.
+
+### Requirements
+* knowledge in the coreboot build system and the concept of stages
+* the KASAN feature can be improved in a way so that the memory space needed
+  during runtime is not on a fixed address provided during compile time but
+  determined during runtime. For this to achieve a small patch to the GCC will
+  be helpful. Therefore minor GCC knowledge would be beneficial.
+* Implementation can be initially done in QEMU and improved on different

+# Flashing firmware tutorial
+
+Updating the firmware is possible using the **internal method**, where the updates
+happen from a running system, or using the **external method**, where the system
+is in a shut down state and an external programmer is attached to write into the
+flash IC.
+
+## Contents
+
+* [Flashing internaly](int_flashrom.md)
+* [Flashing firmware standalone](ext_standalone.md)
+* [Flashing firmware externally supplying direct power](ext_power.md)
+* [Flashing firmware externally without supplying direct power](no_ext_power.md)
+
+## General advice
+
+* It's recommended to only flash the BIOS region.
+* Always verify the firmware image.
+* If you flash externally and have transmission errors:
+  * Use short wires
+  * Reduce clock frequency
+  * Check power supply
+  * Make sure that there are no other bus masters (EC, ME, SoC, ...)
+
+## Internal method
+
+This method using [flashrom] is available on many platforms, as long as they
+aren't locked down.
+
+There are various protection schemes that make it impossible to modify or
+replace a firmware from a running system. coreboot allows to disable these
+mechanisms, making it possible to overwrite (or update) the firmware from a
+running system.
+
+Usually you must use the **external method** once to install a retrofitted
+coreboot and then you can use the **internal method** for future updates.
+
+There are multiple ways to update the firmware:
+* Using flashrom's *internal* programmer to directly write into the firmware
+  flash IC, running on the target machine itself
+* A proprietary software to update the firmware, running on the target machine
+  itself
+* A UEFI firmware update capsule
+
+More details on flashrom's
+* [internal programmer](int_flashrom.md)
+
+## External method
+
+External flashing is possible on many platforms, but requires disassembling
+the target hardware. You need to buy a flash programmer, that
+exposes the same interface as your flash IC (likely SPI).
+
+Please also have a look at the mainboard-specific documentation for details.
+
+After exposing the firmware flash IC, read the schematics and use one of the
+possible methods:
+
+* [Flashing firmware standalone](ext_standalone.md)
+* [Flashing firmware externally supplying direct power](ext_power.md)
+* [Flashing firmware externally without supplying direct power](no_ext_power.md)
+
+**WARNING:** Using the wrong method or accidentally using the wrong pinout might
+  permanently damage your hardware!
+
+**WARNING:** Do not rely on dots *painted* on flash ICs to orient the pins!
+Any dots painted on flash ICs may only indicate if they've been tested.  Dots
+that appear in datasheets to indicate pin 1 correspond to some kind of physical
+marker, such as a drilled hole, or one side being more flat than the other.
+
+## Using a layout file
+On platforms where the flash IC is shared with other components you might want
+to write only a part of the flash IC. On Intel for example there are IFD, ME and
+GBE which don't need to be updated to install coreboot.
+To make [flashrom] only write the *bios* region, leaving Intel ME and Intel IFD
+untouched, you can use a layout file, which can be created with ifdtool and a backup
+of the original firmware.
+
+```bash
+ifdtool -f rom.layout backup.rom
+```
+
+and looks similar to:
+
+```
+00000000:00000fff fd
+00500000:00bfffff bios
+00003000:004fffff me
+00001000:00002fff gbe
+```
+
+By specifying *-l* and *-i* [flashrom] writes a single region:
+```bash
+flashrom -l rom.layout -i bios -w coreboot.rom -p <programmer>
+```
+
+## Using an IFD to determine the layout
+flashrom version 1.0 supports reading the layout from the IFD (first 4KiB of
+the ROM). You don't need to manually specify a layout it, but it only works
+under the following conditions:
+
+* Only available on Intel ICH7+
+* There's only one flash IC when flashing externally
+
+```bash
+flashrom --ifd -i bios -w coreboot.rom -p <programmer>
+```

-Gerrit user roles
------------------
-There are a few relevant roles a user can have on Gerrit:
-
-- The anonymous user can check out source code.
-- A registered user can also comment and give "+1" and "-1" code reviews.
-- A reviewer can also give "+2" code reviews.
-- A core developer can also give "-2" (that is, blocking) code reviews
-  and submit changes.
-
-Anybody can register an account on our instance, using either an
-OpenID provider or OAuth through GitHub or Google.
-
-The reviewer group is still quite open: Any core developer can add
-registered users to that group and should do so once some activity
-(commits, code reviews, and so on) has demonstrated rough knowledge
-of how we handle things.
-
-A core developer should be sufficiently well established in the
-community so that they feel comfortable when submitting good patches,
-when asking for improvements to less good patches and reasonably
-uncomfortable when -2'ing patches. They're typically the go-to
-person for _some_ part of the coreboot tree and ideally listed as its
-maintainer in our MAINTAINERS registry. To become part of this group,
-a candidate developer who already demonstrated proficiency with the
-code base as a reviewer should be nominated, by themselves or others,
-at the regular [coreboot leadership meetings](../community/forums.md)
-where a decision is made.
-
-Core developers are expected to use their privileges for the good of the
-project, which includes any of their own coreboot development but also beyond
-that. They should make sure that [ready changes] don't linger around needlessly
-just because their authors aren't well-connected with core developers but
-submit them if they went through review and generally look reasonable. They're
-also expected to help clean-up breakage as a result of their submissions.
-
-Since the project expects some activity by core developers, long-term absence
-(as in "years") can lead to removal from the group, which can easily be
-reversed after they come back.
 
 Requests for clarification and suggestions for updates to these guidelines
 should be sent to the coreboot mailing list at <coreboot@coreboot.org>.

-## Unconnected and unused pads
-
-In digital electronics, it is generally recommended to tie unconnected GPIOs to
-a defined signal like VCC or GND by setting their direction to output, adding an
-external pull resistor or configuring an internal pull resistor. This is done to
-prevent floating of the pin state, which can cause various issues like EMI,
-higher power usage due to continuously switching logic, etc.
-
-On Intel PCHs from Sunrise Point onwards, termination of unconnected GPIOs is
-explicitly not required, when the input buffer is disabled by setting the bit
-`GPIORXDIS` which effectively disconnects the pad from the internal logic. All
-pads defaulting to GPIO mode have this bit set. However, in the mainboard's
-GPIO configuration the macro `PAD_NC(pad, NONE)` can be used to explicitly
-configure a pad as unconnected.
-
-In case there are no schematics available for a board and the vendor set a
-pad to something like `GPIORXDIS=1`, `GPIOTXDIS=1` with an internal pull
-resistor, an unconnected or otherwise unused pad can be assumed. In this case it
-is recommended to keep the pull resistor, because the external circuit might
-rely on it.
-
-Unconnected pads defaulting to a native function (input and output) usually
-don't need to be configured as GPIO with the `GPIORXDIS` bit set. For clarity
-and documentation purpose the macro may be used as well for them.
-
-Some pads configured as native input function explicitly require external
-pull-ups when being unused, according to the PDGs:
-- eDP_HPD
-- SMBCLK/SMBDATA
-- SML0CLK/SML0DATA/SML0ALERT
-- SATAGP*
-
-When the board was designed correctly, nothing needs to be done for them
-explicitly, while using `PAD_NC(pad, NONE)` can act as documentation. If such a
-pad is missing the external pull resistor due to bad board design, the pad
-should be configured with `PAD_NC(pad, NONE)` anyway to disconnect it
-internally.

-Each GPIO Community has a Pad Configuration Lock register for a GPP allowing locking
-specific register fields in the PAD configuration register.
-
-The Pad Config Lock registers reset type is default hardcoded to **Power Good** and
-it's **not** configurable by GPIO PAD DW0.PadRstCfg. Hence, it may appear that for a GPP,
-the Pad Reset Config (DW0 Bit 31) is configured differently from `Power Good`.
-
-This would create confusion where the Pad configuration is returned to its `default`
-value but remains `locked`, this would prevent software to reprogram the GPP.
-Additionally, this means software can't rely on GPIOs being reset by PLTRST# or Sx entry.
-
-Hence, as per GPIO BIOS Writers Guide (BWG) it's recommended to change the Pad Reset
-Configuration for lock GPP as `Power Good` so that pad configuration and lock bit are
-always in sync and can be reset at the same time.
-
-## Soft Straps
-
-Soft straps, that can be configured by the vendor in the Intel Flash Image Tool
-(FIT), can influence some pads' default mode. It is possible to select either a
-native function or GPIO mode for some pads on non-server SoCs, while on server
-SoCs most pads can be controlled. Thus, it is generally recommended to always
-configure all pads and don't just rely on the defaults mentioned in the
-datasheet(s) which might not reflect what the vendor configured.
-
-## Pad-related known issues and workarounds
-
-### LPC_CLKRUNB blocks S0ix states when board uses eSPI
-
-When using eSPI, the pad implementing `LPC_CLKRUNB` must be set to GPIO mode.
-Other pin settings i.e. Rx path enable/disable, Tx path enable/disable, pull up
-enable/disable etc are ignored. Leaving this pin in native mode will keep the
-LPC Controller awake and prevent S0ix entry. This issues is know at least on
-Apollolake and Geminilake.

-## How to set up a new jenkins builder
-
-### Contact a jenkins admin
-
-Let a jenkins admin know that you’re interested in setting up a jenkins
-build system.
-
-For a permanent build system, this should generally be a dedicated
-machine workstation or server class machine that is not generally being
-used for other purposes.  The coreboot builds are very intensive.
-
-It's also best to be aware that although we don't know of any security
-issues, the jenkins-node image is run with the privileged flag which
-gives the container root access to the build machine.  See
-[this article](https://blog.trendmicro.com/trendlabs-security-intelligence/why-running-a-privileged-container-in-docker-is-a-bad-idea/)
-about why this is discouraged.
-
-It's recommended that you give an admin root access on your machine so
-that they can reset it in case of a failure.  This is not a requirement,
-as the system can just be disabled until someone is available to fix any
-issues.
-
-Currently active Jenkins admins:

-
-### Build Machine requirements
-
-For a builder, we need a very fast system with lots of threads and
-plenty of RAM.  The builder builds and stores the git repos and output
-in tmpfs along with the ccache save area, so if there isn't enough
-memory, the builds will slow down because of smaller ccache areas and
-can run into "out of storage space" errors.
-
-#### Current Build Machines
-
-To give an idea of what a suitable build machine might be, currently the
-coreboot project has 6 active jenkins build machines.
-
-These times are taken from the week of Feb 21 - Feb 28, 2022

-
-
-### Jenkins Builds
-
-There are a number of builds handled by the coreboot jenkins builders,
-for a number of different projects - coreboot, flashrom, memtest86+,
-em100, etc.  Many of these have builders for their current master branch
-as well as Gerrit and [Coverity](coverity.md) builds.
-
-
-#### Long builds - over 90 minutes on congenialbuilder
-There are a few builds that take a long time even on the fastest
-machines.  These tasks run overnight in the US timezones.
-* coreboot_coverity - 9 to 12 hours
-* coreboot_scanbuild - ~3 hours
-* coreboot_toolchain - ~1 hour 45 minutes
-
-
-#### All builds
-
-You can see all the builds in the main jenkins interface:
-[https://qa.coreboot.org/](https://qa.coreboot.org/)
-
-Most of the time on the builders is taken up by the coreboot master and
-coreboot gerrit builds.
-
-* [coreboot gerrit build](https://qa.coreboot.org/job/coreboot-gerrit/)
-([Time trend](https://qa.coreboot.org/job/coreboot-gerrit/buildTimeTrend))
-
-
-* [coreboot master build](https://qa.coreboot.org/job/coreboot/)
- ([Time trend](https://qa.coreboot.org/job/coreboot/buildTimeTrend))
-
-
-### Stress test the machine
-
-Test the machine to make sure that building won't stress the hardware
-too much.  Install stress-ng, then run the stress test for at least an
-hour.
-
-On a system with 32 cores, it was tested with this command:
-
-```sh
-stress-ng --cpu 20 --io 6 --vm 6 --vm-bytes 1G --verify --metrics-brief -t 60m
-```
-
-You can watch the temperature with the sensors package or with ‘acpi -t’
-if your machine supports that.
-
-You can check for thermal throttling by running this command and seeing
-if the values go down on any of the cores after it's been running for a
-while.
-
-```sh
-while [ true ]; do clear; cat /proc/cpuinfo | grep 'cpu MHz' ; sleep 1; done
-```
-
-If the machine throttles or resets, you probably need to upgrade the
-cooling system.

-If you’ve met all the above requirements, and an admin has agreed to set
-up the builder in jenkins, you’re ready to go on to the next steps.
-
-
-### Set up your network so jenkins can talk to the container
-
-Expose a local port through any firewalls you might have on your router.
-This would generally be in the port forwarding section, and you'd just
-forward a port (typically 49151) from the internet directly to the
-builder’s IP address.
-
-You might also want to set up a port to forward to port 22 on your
-machine and set up openssh so you or the jenkins admins can manage
-the machine remotely (if you allow them).
-
-
-### Install and set up docker
-
-Install docker by following [the
-directions](https://docs.docker.com/engine/install/) on the docker site.
-These instructions keep changing, so just check the latest information.
-
-
-### Set up the system for the jenkins builder
-
-As a regular user - *Not root*, run:
-
-```sh
-sudo mkdir -p ${COREBOOT_JENKINS_CACHE_DIR}
-sudo mkdir -p ${COREBOOT_JENKINS_CCACHE_DIR}
-sudo chown $(whoami):$(whoami) ${COREBOOT_JENKINS_CCACHE_DIR}
-sudo chown $(whoami):$(whoami) ${COREBOOT_JENKINS_CACHE_DIR}
-wget http://www.dediprog.com/save/78.rar/to/EM100Pro.rar
-mv EM100Pro.rar ${COREBOOT_JENKINS_CACHE_DIR}
-```
-
-
-#### Set up environment variables
-
-To make configuration and the later commands easier, these should go in
-your shell's .rc file.  Note that you only need to set them if you're
-using something other than the default.
-
-```sh
-# Set the port used on your machine to connect to jenkins.
-export COREBOOT_JENKINS_PORT=49151
-
-# Set the revision of the container from [docker hub](https://hub.docker.com/repository/docker/coreboot/coreboot-sdk)
-export DOCKER_COMMIT=2021-09-23_b0d87f753c
-
-# Set the location of where the jenkins cache directory will be.
-export COREBOOT_JENKINS_CACHE_DIR="/srv/docker/coreboot-builder/cache"
-
-# Set the name of the container
-export COREBOOT_JENKINS_CONTAINER="coreboot_jenkins"
-```
-
-Make sure any variables needed are set in your environment before
-continuing to the next step.
-
-
-### Using the Makefile for docker installation
-
-From the coreboot directory, run
-
-```sh
-make -C util/docker help
-```
-
-This will show you the available targets and variables needed:

-
-
-### Install the coreboot jenkins builder
-
-```sh
-make -C util/docker docker-jenkins-server
-```
-
-Your installation is complete on your side.
-
-### Tell the Admins that the machine is set up
-Let the admins know that the builder is set up so they can set up the
-machine profile on qa.coreboot.org.
-
-They need to know:
-*   Your external IP address or domain name.  If you don’t have a static
-    IP, make sure you have a dynamic dns hostname configured.
-*   The port on your machine and firewall that’s exposed for jenkins:
-    `$COREBOOT_JENKINS_PORT`
-*   The core count of the machine.
-*   How much memory is available on the machine.  This helps determine
-    the amount of memory used for ccache.
-
-
-### First build
-On the first build after a machine is reset, it will frequently take
-an hour to do the entire what-jenkins-does build while the ccache
-is getting filled up and the entire coreboot repo gets downloaded.  As
-the ccache gets populated, the build time will drop.
-
-
-## Additional Information
-
-
-### How to log in to the docker instance for debugging
-
-```sh
-make -C util/docker docker-jenkins-attach
-su coreboot
-cd ~/slave-root/workspace
-bash
-```
-
-
-WARNING: This should not be used to make changes to the build system,
-but just to debug issues. Changes to the build system image are highly
-discouraged as it leads to situations where patches can pass the build
-testing on one builder and fail on another builder. Any changes that are
-made in the image will be lost on the next update, so if you
-accidentally change something, you can remove the containers and images,
-then update to get a fresh installation.
-
-
-### How to download containers/images for a fresh installation and remove old containers
-
-To delete the old containers & images:
-
-```sh
-docker stop $COREBOOT_JENKINS_CONTAINER
-docker rm $COREBOOT_JENKINS_CONTAINER
-docker images # lists all existing images
-docker rmi XXXX # Use the image ID found in the above command.
-```
-
-To get and run the new coreboot-jenkins image, change the value in the
-`DOCKER_COMMIT` variable to the new image value.
-
-```sh
-make -C util/docker docker-jenkins-server
-```
-
-#### Getting ready to push the docker images
-
-Set up an account on hub.docker.com
-
-Get an admin to add the account to the coreboot team on hub.docker.com
-
-[https://hub.docker.com/u/coreboot/dashboard/teams/?team=owners](https://hub.docker.com/u/coreboot/dashboard/teams/?team=owners)
-
-Make sure your credentials are configured on your host machine by
-running
-
-```sh
-docker login
-```
-
-This will prompt you for your docker username, password, and your email
-address, and write out to ~/.docker/config.json.  Without this file, you
-won’t be able to push the images.
-
-#### Updating the Dockerfiles
-
-The coreboot-sdk Dockerfile will need to be updated when any additional
-dependencies are added.  Both the coreboot-sdk and the
-coreboot-jenkins-node Dockerfiles will need to be updated to the new
-version number and git commit id anytime the toolchain is updated. Both
-files are stored in the coreboot repo under coreboot/util/docker.
-
-Read the [dockerfile best practices](https://docs.docker.com/v1.8/articles/dockerfile_best-practices/)
-page before updating the files.
-
-#### Rebuilding the coreboot-sdk docker image to update the toolchain
-
-```sh
-make -C util/docker coreboot-sdk
-```
-
-This takes a relatively long time.
-
-#### Test the coreboot-sdk docker image
-
-There are two methods of running the docker image - interactively as a
-shell, or doing the build directly.  Running interactively as a shell is
-useful for early testing, because it allows you to update the image
-(without any changes getting saved) and re-test builds.  This saves the
-time of having to rebuild the image for every issue you find.
-
-#### Running the docker image interactively
-
-Run:
-
-```sh
-make -C util/docker docker-jenkins-server
-make -C util/docker docker-jenkins-attach
-```
-
-#### Running the build directly
-
-From the coreboot directory:
-
-```sh
-make -C util/docker docker-build-coreboot
-```
-
-You’ll also want to test building the other projects and payloads:
-ChromeEC, flashrom, memtest86+, em100, Grub2, SeaBIOS, iPXE, coreinfo,
-nvramcui, tint...
-
-#### Pushing the coreboot-sdk image to hub.docker.com for use
-
-When you’re satisfied with the testing, push the coreboot-sdk image to
-the hub.docker.com
-
-```sh
-make -C util/docker upload-coreboot-sdk
-```
-
-#### Building and pushing the coreboot-jenkins-node docker image
-
-This docker image is pretty simple, so there’s not really any testing
-that needs to be done.
-
-```sh
-make -C util/docker coreboot-jenkins-node
-make -C util/docker upload-coreboot-jenkins-node
-```
-
-### Coverity Setup
-
-To run coverity jobs, the builder needs to have the tools available, and
-to be marked as a coverity builder.
-
-
-#### Set up the Coverity tools
-
-Download the Linux-64 coverity build tool and decompress it into your
-cache directory as defined by the `$COREBOOT_JENKINS_CACHE_DIR` variable
-on the jenkins server.
-
-[https://scan.coverity.com/download](https://scan.coverity.com/download)
-
-Rename the directory from its original name
-(cov-analysis-linux64-7.7.0.4) to ‘coverity’, or better, create a
-symlink:
-
-```sh
-ln -s cov-analysis-linux64-7.7.0.4 coverity
-```
-
-
-Let the admins know that the ‘coverity’ label can be added to the
-builder.

-# Coverity Scan for open source firmware
-
-## What’s Coverity and Coverity Scan?
-
-Coverity is a static analysis tool. It hooks into the build process
-and in addition to the compiler creating object files, Coverity collects
-information about the code. That data is then processed in a separate pass
-to identify common programming errors, like out of bounds accesses in C.
-
-Coverity Scan is an online service for Open Source projects providing this
-analysis for free. The analysis pass is done on their servers and issues
-can be handled in their [web UI](https://scan.coverity.com/).
-
-The Scan service has some quotas based on code size to avoid overloading
-the system, but even at one build per week, that’s usually good enough
-because the identified issues still need to be triaged and fixed or they
-will simply be re-identified next week.
-
-### Triage?
-
-The Web UI looks a bit like an issue tracker, even if it’s not a very
-good one. It’s possible to mark identified issues as valid or invalid,
-and annotate them with metadata which CLs fix them. The latter isn’t
-strictly necessary because Coverity Scan simply marks issues it can’t
-find anymore as fixed, but at times it helped identify issues that made
-a comeback.
-
-### Alternatives
-
-There’s also clang’s scan-build, which is fully open-source, and
-finds different issues. As such, it’s less of an alternative and more
-of a complement.
-
-There’s a regular run of that for coreboot but not for the other projects
-hosted at coreboot.org.
-
-One downside is that it emits a bunch of HTML to report on issues,
-but there’s no interactivity (e.g. marking issues solved), no way
-to merge multiple builds (e.g. multiple board builds of a single tree)
-or a simple way to extract burndown charts and the like from that.
-
-#### Looking for a project?
-
-On the upside, it can emit the data in a machine readable format, so if
-anybody needs a project, a scan-build web-frontend like Coverity Scan would
-be feasible without having to go through scan-build’s guts, just by parsing
-text files - plus all the stateful and web parts to build on top.
-
-## Logging into Coverity Scan
-
-Coverity Scan needs an account. It supports its own accounts and GitHub
-OAuth.
-
-Access to the dashboards needs approval: Request and you shall receive.
-
-## coreboot & friends and Coverity Scan
-
-coreboot, flashrom, Chromium EC and other projects of that family have
-been made Coverity aware, that is, their build systems support building
-with a custom compiler configuration passed in “just right” to enable
-Coverity to add its hooks.
-
-The public coreboot CI system at
-[https://qa.coreboot.org/](https://qa.coreboot.org/) regularly does
-builds with Coverity and sends them off to Coverity Scan.
-
-Specifically, it covers:
-
-* Chromium EC: [Coverity Scan site][crECCoverity] ([build job][crECBuildJob])
-* coreboot: [Coverity Scan site][corebootCoverity] ([build job][corebootBuildJob]), [scan-build output][corebootScanBuild] ([build job][corebootScanBuildJob])
-* em100: [Coverity Scan site][em100Coverity] ([build job][em100BuildJob])
-* fcode-utils: [Coverity Scan site][fcodeUtilsCoverity] ([build job][fcodeUtilsBuildJob])
-* flashrom: [Coverity Scan site][flashromCoverity] ([build job][flashromBuildJob])
-* memtest86+: [Coverity Scan site][memtestCoverity] ([build job][memtestBuildJob])
-* vboot: [Coverity Scan site][vbootCoverity] ([build job][vbootBuildJob])

-
-Some projects (e.g. Chromium EC) build a different subset of boards on
-each run, ensuring that everything is analyzed eventually. The downside
-is that coverity issues pop up and disappear somewhat randomly as they
-are discovered and go unnoticed in a later build.
-
-More projects that are hosted on review.coreboot.org (potentially as a
-mirror, like vboot and EC) could be served through that pipeline. Reach
-out to {stepan,patrick,martin}@coreboot.org.

-```
-
-In general, flashing is possible internally and from an external header. It
-might be necessary to specify the chip type; `MX25L1605D/MX25L1608D/MX25L1673E`
-is the correct one, not `MX25L1605`.
-
-### Internal flashing
-
-Internal access to the flash chip is unrestricted. When installing coreboot,
-only the BIOS region should be updated by passing the `--ifd` and `-i bios`
-parameters to flashrom. A full backup is advisable.
-
-Here is an example:
-
-```
-$ sudo flashrom \
-  -p internal \
-  -c "MX25L1605D/MX25L1608D/MX25L1673E" \
-  -r backup.rom
-$ sudo flashrom \
-  -p internal \
-  -c "MX25L1605D/MX25L1608D/MX25L1673E" \
-  --ifd -i bios \
-  -w coreboot.rom
-```
-
-```eval_rst
-In addition to the information here, please see the
-:doc:`../../tutorial/flashing_firmware/index`.
-```
-
-### External flashing
-
-The SPI flash chip on this board can be flashed externally through the
-SPI_ROM1 header while the board is off and disconnected from power. There
-seems to be a diode that prevents the external programmer from powering the
-whole board.
-
-The signal assignment on the header is identical to the pinout of the flash
-chip. The pinout diagram below is valid when the PCI slots are on the left
-and the CPU is on the right. Note that HOLD# and WP# must be pulled high
-(to VCC) to be able to flash the chip.
-
-                +---+---+
-     SPI_CSn <- | x | x | -> VCC
-                +---+---+
-    SPI_MISO <- | x | x | -> HOLDn
-                +---+---+
-         WPn <- | x | x | -> SPI_CLK
-                +---+---+
-         GND <- | x | x | -> SPI_MOSI
-                +---+---+
-
-## Intel Management Engine
-
-The Intel Management Engine (ME) can be disabled by setting the ME_DISABLE
-jumper on the board. It pulls GPIO33 on the ICH10 low, causing the "Flash
-Descriptor Security Override Strap" to be set. This disables the ME and also
-disables any read/write restrictions to the flash chip that may be set in the
-Intel Flash Descriptor (IFD) (none on this board). Note that changing this
-jumper only comes into effect when starting the board from a shutdown or
-suspend state, not during normal operation.
-
-To completely remove the ME blob from the flash image and to decrease the size
-of the ME region, thus increasing the size of the BIOS region, `me_cleaner` can
-be used with the `-t`, `-r` and `-S` options.
-
-## Fan control
-
-There are two fan connectors that can be controlled individually. CPU_FAN
-can only control a fan by a PWM signal and SYS_FAN only by voltage. See
-the mainboard's `devicetree.cb` file for how coreboot configures the Super
-I/O to control the fans.
-
-## Variants
-
-Various similar mainboards exist, like the Acer Q45T-AM. During a discussion
-in #coreboot on IRC, ECS was suspected to be the original designer of this
-series of mainboards. They have similar models such as the ECS G43T-WM.

-### Internal programming
-
-The main SPI flash can be accessed using flashrom. By default, only

-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.
-
-```eval_rst
-In addition to the information here, please see the
-:doc:`../../tutorial/flashing_firmware/index`.
-```
-
-## Hardware monitoring and fan control
-
-There are two fan headers for the CPU cooler, CPU_FAN1 and CPU_FAN2. They share
-a single fan tachometer input on the Super I/O while some dedicated logic
-selects which one is allowed to reach it. Two GPIO pins on the Super I/O are
-used to control that logic. The firmware has to set them; coreboot selects
-CPU_FAN1 by default, but the user can change that setting if it was built with
-CONFIG_USE_OPTION_TABLE:
-
-```
-$ sudo nvramtool -e cpu_fan_header
-[..]
-$ sudo nvramtool -w cpu_fan_header=CPU_FAN2
-$ sudo nvramtool -w cpu_fan_header=None
-$ sudo nvramtool -w cpu_fan_header=Both
-```
-
-The setting will take effect after a reboot. Selecting and connecting both fan
-headers is possible but the Super I/O will report wrong fan speeds.
-
-Currently there is no automatic, OS-independent fan control, but a software
-like `fancontrol` from the lm-sensors package can be used instead.
-
-## Serial port header
-
-Serial port 1, provided by the Super I/O, is exposed on a pin header. The
-RS-232 signals are assigned to the header so that its pin numbers map directly
-to the pin numbers of a DE-9 connector. If your serial port doesn't seem to
-work, check if your bracket expects a different assignment. Also don't try to
-connect it directly to a device that operates at TTL levels - it would need a
-level converter like a MAX232.
-
-Here is a top view of the serial port header found on this board:
-
-                 +---+---+
-             N/C |   | 9 | RI  -> pin 9
-                 +---+---+
-    Pin 8 <- CTS | 8 | 7 | RTS -> pin 7
-                 +---+---+
-    Pin 6 <- DSR | 6 | 5 | GND -> pin 5
-                 +---+---+
-    Pin 4 <- DTR | 4 | 3 | TxD -> pin 3
-                 +---+---+
-    Pin 2 <- RxD | 2 | 1 | DCD -> pin 1
-                 +---+---+
-
-## eSATA
-
-The eSATA port on the rear I/O panel and the internal connector SATA3_A1 share
-the same controller port on the ASM1061. Attaching an eSATA drive causes a
-multiplexer chip to disconnect the internal port from the SATA controller and
-connect the eSATA port instead. This can be seen on GP23 of the Super I/O
-GPIOs: it is '0' when something is connected to the eSATA port and '1'
-otherwise.

-+ temp2 (CPU) can be used to control fan2
-
-### Manual fan speed
-
-These commands set the chassis fans to a constant speed:
-
-    # Use PWM output
-    echo 1 >/sys/class/hwmon/hwmon2/pwm1_mode
-    # Set to manual mode
-    echo 1 >/sys/class/hwmon/hwmon2/pwm1_enable
-    # Set relative speed: 0 (stop) to 255 (full)
-    echo 150 >/sys/class/hwmon/hwmon2/pwm1
-
-### Automatic fan speed
-
-The W83667HG can adjust fan speeds when things get too warm. These settings will
-control the chassis fans:
-
-    # Set to "Thermal Cruise" mode
-    echo 2 >/sys/class/hwmon/hwmon2/pwm1_enable
-    # Target temperature: 60°C
-    echo 60000 >/sys/class/hwmon/hwmon2/pwm1_target
-    # Minimum fan speed when spinning up
-    echo 135 >/sys/class/hwmon/hwmon2/pwm1_start_output
-    # Minimum fan speed when spinning down
-    echo 135 >/sys/class/hwmon/hwmon2/pwm1_stop_output
-    # Tolerance: 2°C
-    echo 2000 >/sys/class/hwmon/hwmon2/pwm1_tolerance
-    # Turn fans off after 600 seconds when below defined range
-    echo 600000 >/sys/class/hwmon/hwmon2/pwm1_stop_time
-
-You can also control the CPU fan with similar rules:
-
-    # Switch to "Thermal Cruise" mode

-
-### How to flash
-
-Unlike ordinary desktop boards, the BIOS version 3202 of ASUS P8C WS does not
-apply any write protection, so the main SPI flash can be accessed using
-[flashrom], and the whole flash is writable.
-
-The following command may be used to flash coreboot. (To do so, linux kernel
-should be started with `iomem=relaxed`)
-
-```
-# flashrom -p internal -w coreboot.rom
-```
-
-The flash chip is a socketed DIP-8 SPI flash, so it's also easy to remove and
-flash externally.

-On Asus vendor firmware, other than the default config already supported here,

-and onboard ASM1061 disabled" and "PCIEX_16_3 as x1, but PCIe Port 4 to PCIEX_1_2,
-with onboard ASM1061 disabled".
-
-Configuring PCIEX_16_3 as x4 needs to program 0x3 to the LSB of PCHSTRP9, but
-also needs to configure GPIOs in the Super I/O chip different than the default
-config in this board's override tree.
-
-Configuring PCIe Port 4 to PCIEX_1_2 needs to configure GPIOs in the Super I/O
-chip differently than the default config.
-
-I have tried a lot, but sadly I am unable to produce the same result as the vendor
-firmware.

-## Building coreboot
-```bash

-make

-
-This builds coreboot with no payload.
-
-## Payloads
-You can configure ELF or `skiboot` payload via `make menuconfig`. In either case
-you might need to adjust "ROM chip size" and make it large enough to accommodate
-the payload (see how much space it needs in the error you get if it doesn't
