+# Adding new devices to a device tree
+
+## Introduction
+
+ACPI exposes a platform-independent interface for operating systems to perform
+power management and other platform-level functions.  Some operating systems
+also use ACPI to enumerate devices that are not immediately discoverable, such
+as those behind I2C or SPI buses (in contrast to PCI).  This document discusses
+the way that coreboot uses the concept of a "device tree" to generate ACPI
+tables for usage by the operating system.
+
+## Devicetree and overridetree (if applicable)
+
+For mainboards that are organized around a "reference board" or "baseboard"
+model (see ``src/mainboard/google/octopus`` or ``hatch`` for examples), there is
+typically a devicetree.cb file that all boards share, and any differences for a
+specific board ("variant") are captured in the overridetree.cb file.  Any
+settings changed in the overridetree take precedence over those in the main
+devicetree.  Note, not all mainboards will have the devicetree/overridetree
+distinction, and may only have a devicetree.cb file.  Or you can always just
+write the ASL (ACPI Source Language) code yourself.
+
+### 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.
+
+## Device drivers
+
+Let's take a look at an example entry from
+``src/mainboard/google/hatch/variants/hatch/overridetree.cb``:
+
+```
+device pci 15.0 on
+	chip drivers/i2c/generic
+		register "hid" = ""ELAN0000""
+		register "desc" = ""ELAN Touchpad""
+		register "irq" = "ACPI_IRQ_WAKE_LEVEL_LOW(GPP_A21_IRQ)"
+		register "wake" = "GPE0_DW0_21"
+		device i2c 15 on end
+	end
+end # I2C #0
+```
+
+When this entry is processed during ramstage, it will create a device in the
+ACPI SSDT table (all devices in devicetrees end up in the SSDT table).  The ACPI
+generation routines in coreboot actually generate the raw bytecode that
+represents the device's structure, but looking at ASL code is easier to
+understand; see below for what the disassembled bytecode looks like:
+
+```
+Scope (\_SB.PCI0.I2C0)
+{
+    Device (D015)
+    {
+        Name (_HID, "ELAN0000")  // _HID: Hardware ID
+        Name (_UID, Zero)  // _UID: Unique ID
+        Name (_DDN, "ELAN Touchpad")  // _DDN: DOS Device Name
+        Method (_STA, 0, NotSerialized)  // _STA: Status
+        {
+            Return (0x0F)
+        }
+        Name (_CRS, ResourceTemplate ()  // _CRS: Current Resource Settings
+        {
+            I2cSerialBusV2 (0x0015, ControllerInitiated, 400000,
+                AddressingMode7Bit, "\\_SB.PCI0.I2C0",
+                0x00, ResourceConsumer, , Exclusive, )
+            Interrupt (ResourceConsumer, Level, ActiveLow, ExclusiveAndWake, ,, )
+            {
+                0x0000002D,
+            }
+        })
+        Name (_S0W, ACPI_DEVICE_SLEEP_D3_HOT)  // _S0W: S0 Device Wake State
+        Name (_PRW, Package (0x02)  // _PRW: Power Resources for Wake
+        {
+            0x15, // GPE #21
+            0x03  // Sleep state S3
+        })
+    }
+}
+```
+
+You can see it generates _HID, _UID, _DDN, _STA, _CRS, _S0W, and _PRW
+names/methods in the Device's scope.
+
+## Utilizing a device driver
+
+The device driver must be enabled for your build.  There will be a CONFIG option
+in the Kconfig file in the directory that the driver is in (e.g.,
+``src/drivers/i2c/generic`` contains a Kconfig file; the option here is named
+CONFIG_DRIVERS_I2C_GENERIC).  The config option will need to be added to your
+mainboard's Kconfig file (e.g., ``src/mainboard/google/hatch/Kconfig``) in order
+to be compiled into your build.
+
+## Diving into the above example:
+
+Let's take a look at how the devicetree language corresponds to the generated
+ASL.
+
+First, note this:
+
+```
+    chip drivers/i2c/generic
+```
+
+This means that the device driver we're using has a corresponding structure,
+located at ``src/drivers/i2c/generic/chip.h``, named **struct
+drivers_i2c_generic_config** and it contains many properties you can specify to
+be included in the ACPI table.
+
+### hid
+
+```
+    register "hid" = ""ELAN0000""
+```
+
+This corresponds to **const char *hid** in the struct.  In the ACPI ASL, it
+translates to:
+
+```
+    Name (_HID, "ELAN0000") // _HID: Hardware ID
+```
+
+under the device.  **This property is used to match the device to its driver
+during enumeration in the OS.**
+
+### desc
+
+```
+    register "desc" = ""ELAN Touchpad""
+```
+
+corresponds to **const char *desc** and in ASL:
+
+```
+    Name (_DDN, "ELAN Touchpad") // _DDN: DOS Device Name
+```
+
+### irq
+
+It also adds the interrupt,
+
+```
+    Interrupt (ResourceConsumer, Level, ActiveLow, ExclusiveAndWake, ,, )
+    {
+        0x0000002D,
+    }
+```
+
+which comes from:
+
+```
+    register "irq" = "ACPI_IRQ_WAKE_LEVEL_LOW(GPP_A21_IRQ)"
+```
+
+The GPIO pin IRQ settings control the "Level", "ActiveLow", and
+"ExclusiveAndWake" settings seen above (level means it is a level-triggered
+interrupt as opposed to edge-triggered; active low means the interrupt is
+triggered when the signal is low).
+
+Note that the ACPI_IRQ_WAKE_LEVEL_LOW macro informs the platform that the GPIO
+will be routed through SCI (ACPI's System Control Interrupt) for use as a wake
+source.  Also note that the IRQ names are SoC-specific, and you will need to
+find the names in your SoC's header file.  The ACPI_* macros are defined in
+``src/arch/x86/include/acpi/acpi_device.h``.
+
+Using a GPIO as an IRQ requires that it is configured in coreboot correctly.
+This is often done in a mainboard-specific file named ``gpio.c``.
+
+### wake
+
+The last register is:
+
+```
+    register "wake" = "GPE0_DW0_21"
+```
+
+which indicates that the method of waking the system using the touchpad will be
+through a GPE, #21 associated with DW0, which is set up in devicetree.cb from
+this example.  The "21" indicates GPP_X21, where GPP_X is mapped onto DW0
+elsewhere in the devicetree.
+
+The last bit of the definition of that device includes:

+
+### _S0W (S0 Device Wake State)
+_S0W indicates the deepest S0 sleep state this device can wake itself from,
+which in this case is ACPI_DEVICE_SLEEP_D3_HOT, representing _D3hot_.
+
+### _PRW (Power Resources for Wake)
+_PRW indicates the power resources and events required for wake.  There are no
+dependent power resources, but the GPE (GPE0_DW0_21) is mentioned here (0x15),
+as well as the deepest sleep state supporting waking the system (3), which is
+S3.
+
+### _STA (Status)
+The _STA method is generated automatically, and its values, 0xF, indicates the
+following:
+
+    Bit [0] – Set if the device is present.
+    Bit [1] – Set if the device is enabled and decoding its resources.
+    Bit [2] – Set if the device should be shown in the UI.
+    Bit [3] – Set if the device is functioning properly (cleared if device failed its diagnostics).
+
+### _CRS (Current resource settings)
+The _CRS method is generated automatically, as the driver knows it is an I2C
+controller, and so specifies how to configure the controller for proper
+operation with the touchpad.
+
+```
+Name (_CRS, ResourceTemplate ()  // _CRS: Current Resource Settings

+# Accounts on coreboot.org
+
+There are a number of places where you can benefit from creaating an account
+in our community. Since there is no single sign-on system in place (at this
+time), they come with their own setup routines.
+
+## Gerrit code review
+We exchange and review patches to the code using our [Gerrit code review
+system](https://review.coreboot.org).
+
+It allows logging in with a Google or GitHub account using OAuth2 as well
+as with any OpenID provider that you may already use.
+
+On the [settings screen](https://review.coreboot.org/settings) you can register
+all your email addresses you intend to use in the context of coreboot
+development so that commits with your email address in them are associated with
+you properly.
+
+### https push access
+When using the https URLs to git repositories, you can push with the "HTTP
+Credentials" you can have Gerrit generate for you on that page. By default,
+git uses `$HOME/.netrc` for http authentication data, so add a line there
+stating:
+
+    machine review.coreboot.org login $your-user-name password $your-password
+
+### Gerrit user avatar
+To setup an avatar to show in Gerrit, clone the avatars repository at
+https://review.coreboot.org/gerrit-avatars.git and add a file named
+$your-user-ID.jpg (the user ID is a number shown on the [settings screen](https://review.coreboot.org/settings)).
+The image must be provided in JPEG format, must be square and have at most 50000
+bytes.
+
+After you push for review, the system will automatically verify your change
+and, if adhering to these constraints, approve it. You can then immediately
+submit it.
+
+## Issue tracker
+We have an [issue tracker](https://ticket.coreboot.org) that is used for
+coreboot and related code, such as libpayload, as well as for the project's
+infrastructure.

+Data structures
+---------------
+
+Data structures that have visibility outside the single-threaded
+environment they are created and destroyed in should always have
+reference counts. In the kernel, garbage collection doesn't exist (and
+outside the kernel garbage collection is slow and inefficient), which
+means that you absolutely _have_ to reference count all your uses.
+
+Reference counting means that you can avoid locking, and allows multiple
+users to have access to the data structure in parallel - and not having
+to worry about the structure suddenly going away from under them just
+because they slept or did something else for a while.
+
+Note that locking is _not_ a replacement for reference counting.
+Locking is used to keep data structures coherent, while reference
+counting is a memory management technique. Usually both are needed, and
+they are not to be confused with each other.
+
+Many data structures can indeed have two levels of reference counting,
+when there are users of different "classes". The subclass count counts
+the number of subclass users, and decrements the global count just once
+when the subclass count goes to zero.
+
+Examples of this kind of "multi-level-reference-counting" can be found
+in memory management ("struct mm_struct": mm_users and mm_count),
+and in filesystem code ("struct super_block": s_count and
+s_active).
+
+Remember: if another thread can find your data structure, and you don't
+have a reference count on it, you almost certainly have a bug.

-not required to use `enum cb_err` error codes to return these errors.)
-
-coreboot also has the `die()` function that completely halts execution. `die()`
-should only be used as a last resort, since it results in the worst user
-experience (bricked system). It is generally preferrable to continue executing
-even after a problem was encountered that might be fatal (e.g. SPI clock
-couldn't be configured correctly), because a slight chance of successfully
-booting is still better than not booting at all. The only cases where `die()`
-should be used are:
-
-1. There is no (simple) way to continue executing. For example, when loading the
-   next stage from SPI flash fails, we don't have any more code to execute. When
-   memory initialization fails, we have no space to load the ramstage into.
-
-2. Continuing execution would pose a security risk. All security features in
-   coreboot are optional, but when they are configured in the user must be able
-   to rely on them. For example, if CBFS verification is enabled and the file
-   hash when loading the romstage doesn't match what it should be, it is better
-   to stop execution than to jump to potentially malicious code.
-
-In addition to normal error logging with `printk()`, coreboot also offers the
-`assert()` macro. `assert()` should be used judiciously to confirm that
-conditions are true which the programmer _knows_ to be true, in order to catch
-programming errors and incorrect assumptions. It is therefore different from a
-normal `if ()`-check that is used to actually test for things which may turn
-out to be true or false based on external conditions. For example, anything
-that involves communicating with hardware, such as whether an attempt to read
-from SPI flash succeeded, should _not_ use `assert()` and should instead just
-be checked with a normal `if ()` and subsequent manual error handling. Hardware
-can always fail for various reasons and the programmer can never 100% assume in
-advance that it will work as expected. On the other hand, if a function takes a
-pointer parameter `ctx` and the contract for that function (as documented in a
-comment above its declaration) specifies that this parameter should point to a
-valid context structure, then adding an `assert(ctx)` line to that function may
-be a good idea. The programmer knows that this function should never be called
-with a NULL pointer (because that's how it is specified), and if it was actually
-called with a NULL pointer that would indicate a programming error on account of
-the caller.
-
-`assert()` can be configured to either just print an error message and continue
-execution (default), or call `die()` (when `CONFIG_FATAL_ASSERTS` is set).
-Developers are encouraged to always test their code with this option enabled to
-make assertion errors (and therefore bugs) more easy to notice. Since assertions
-thus do not always stop execution, they should never be relied upon to be the
-sole guard against conditions that really _need_ to stop execution (e.g.
-security guarantees should never be enforced only by `assert()`).

-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.
-
-Refactoring
------------
-Because refactoring existing code can add bugs to tested code, any
-refactors should be done only with serious consideration. Refactoring
-for style differences should only be done if the existing style
-conflicts with a documented coreboot guideline. If you believe that the
-style should be modified, the pros and cons can be discussed on the
-mailing list and in the coreboot leadership meeting.
-
-Similarly, the original author should be respected. Changing working
-code simply because of a stylistic disagreement is *prohibited*. This is
-not saying that refactors that are objectively better (simpler, faster,
-easier to understand) are not allowed, but there has to be a definite
-improvement, not simply stylistic changes.
-
-Basically, when refactoring code, there should be a clear benefit to
-the project and codebase. The reviewers and submitters get to make the
-call on how to interpret this.
-
-When refactoring, adding unit tests to verify that the post-change
-functionality matches or improves upon pre-change functionality is
-encouraged.

-## Organization admins
-
-The *organization admins* are managing the GSoC program for the coreboot
-organization.
-
-The organization admins are:
-
-  * Felix Singer (primary)
-  * Martin Roth
-  * David Hendricks
-
-
-## Contacts
-
-If you are interested in participating in GSoC as a contributor or mentor,
-please have a look at our [community forums] and reach out to us. Working closely
-with the community is highly encouraged, as we've seen that our most successful
-contributors are generally very involved.
-
-
-## Why work on coreboot for GSoC?
-
-  * 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 [small 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.

-# CBFS SMBIOS hooks
-
-The document describes the coreboot options how to make CBFS files populate
-platform-unique SMBIOS data.
-
-## SMBIOS Serial Number
-
-The [DMTF SMBIOS specification] defines a field in the type 1 System
-Information and type 2 Baseboard Information called Serial Number. It
-is a null-terminated string field assumed to be unique per platform. Certain
-mainboard ports have SMBIOS hooks to generate the Serial Numbers from external
-data, e.g. Lenovo Thinkpads (see DRIVER_LENOVO_SERIALS). This driver aims to
-provide an option to populate the Serial Numbers from CBFS for boards that
-can't generate the it from any source.
-
-### Usage
-
-In the coreboot configuration menu (`make menuconfig`) go to `Generic Drivers`
-and select an option `Serial number in CBFS`. The Kconfig system will enable
-`DRIVERS_GENERIC_CBFS_SERIAL` and the relevant code parts will be compiled into
-coreboot image.
-
-After the coreboot build for your board completes, use the cbfstool to include
-the file containing the serial number:
-
-```shell
-./build/cbfstool build/coreboot.rom add -n serial_number -t raw -f /path/to/serial_file.txt
-```
-
-Where `serial_file.txt` is the unterminated string representation of the SMBIOS
-type 1 or type 2 Serial Number, e.g. `5Q4Q7Y1`. If you use vboot with 1 or 2 RW
-partitions you will have to specify the RW regions where the file is going to
-be added too. By default the RW CBFS partitions are truncated, so the files
-would probably not fit, one needs to expand them first.
-
-```shell
-./build/cbfstool build/coreboot.rom expand -r FW_MAIN_A
-./build/cbfstool build/coreboot.rom add -n serial_number -t raw \
-	-f /path/to/serial_file.txt -r FW_MAIN_A
-./build/cbfstool build/coreboot.rom truncate -r FW_MAIN_A
-
-./build/cbfstool build/coreboot.rom expand -r FW_MAIN_B
-./build/cbfstool build/coreboot.rom add -n serial_number -t raw \
-	-f /path/to/serial_file.txt -r FW_MAIN_B
-./build/cbfstool build/coreboot.rom truncate -r FW_MAIN_B
-```
-
-By default cbfstool adds files to COREBOOT region only, so when vboot is
-enabled and the platform is booting from RW partition, the file would not be
-picked up by the driver.
-
-One may retrieve the Serial Number from running system (if it exists) using one
-of the following commands:
-
-```shell
-# Type 1
-echo -n `sudo dmidecode -s system-serial-number` > serial_file.txt
-# OR Type 2
-echo -n `sudo dmidecode -s baseboard-serial-number` > serial_file.txt
-```
-
-Ensure the file does not end with whitespaces like LF and/or CR. The above
-commands will not add any whitespaces. The driver automatically terminates the
-Serial Number with the NULL character. If the CBFS file is not present, the
-driver will fall back to the string defined in `MAINBOARD_SERIAL_NUMBER` build
-option.
-
-Please note that this driver provides `smbios_mainboard_serial_number` hook
-overriding the default implementation which returns `MAINBOARD_SERIAL_NUMBER`
-build option. If you wish to populate only type 2 Serial Number field your
-board code needs to implement `smbios_system_serial_number`, otherwise the weak
-implementation of `smbios_system_serial_number` will call
-`smbios_mainboard_serial_number` from the `DRIVERS_GENERIC_CBFS_SERIAL`
-implementation overriding it. So selecting the `DRIVERS_GENERIC_CBFS_SERIAL`
-has a side-effect of populating both SMBIOS type 1 and type 2 Serial Numbers
-if the board does not implement its own `smbios_system_serial_number`.
-
-There is also SMBIOS type 3 Chassis Information Serial Number, but it is not
-populated by `DRIVERS_GENERIC_CBFS_SERIAL` nor by the default weak
-implementation (returns empty string). If you wish to populate type 3 Serial
-Number, your board code should override the default
-`smbios_chassis_serial_number` weak implementation.
-
-## SMBIOS System UUID
-
-The [DMTF SMBIOS specification] defines a field in the type 1 System
-Information Structure called System UUID. It is a 16 bytes value compliant with
-[RFC4122] and assumed to be unique per platform. Certain mainboard ports have
-SMBIOS hooks to generate the UUID from external data, e.g. Lenovo Thinkpads
-(see DRIVER_LENOVO_SERIALS). This driver aims to provide an option to populate
-the UUID from CBFS for boards that can't generate the UUID from any source.
-
-### Usage
-
-In the coreboot configuration menu (`make menuconfig`) go to `Generic Drivers`
-and select an option `System UUID in CBFS`. The Kconfig system will enable
-`DRIVERS_GENERIC_CBFS_UUID` and the relevant code parts will be compiled into
-coreboot image.
-
-After the coreboot build for your board completes, use the cbfstool to include
-the file containing the UUID:
-
-```shell
-./build/cbfstool build/coreboot.rom add -n system_uuid -t raw -f /path/to/uuid_file.txt
-```
-
-Where `uuid_file.txt` is the unterminated string representation of the SMBIOS
-type 1 UUID, e.g. `4c4c4544-0051-3410-8051-b5c04f375931`. If you use vboot with
-1 or 2 RW partitions you will have to specify the RW regions where the file is
-going to be added too. By default the RW CBFS partitions are truncated, so the
-files would probably not fit, one needs to expand them first.
-
-```shell
-./build/cbfstool build/coreboot.rom expand -r FW_MAIN_A
-./build/cbfstool build/coreboot.rom add -n system_uuid -t raw \
-	-f /path/to/uuid_file.txt -r FW_MAIN_A
-./build/cbfstool build/coreboot.rom truncate -r FW_MAIN_A
-
-./build/cbfstool build/coreboot.rom expand -r FW_MAIN_B
-./build/cbfstool build/coreboot.rom add -n system_uuid -t raw \
-	-f /path/to/uuid_file.txt -r FW_MAIN_B
-./build/cbfstool build/coreboot.rom truncate -r FW_MAIN_B
-```
-
-By default cbfstool adds files to COREBOOT region only, so when vboot is
-enabled and the platform is booting from RW partition, the file would not be
-picked up by the driver.
-
-One may retrieve the UUID from running system (if it exists) using the
-following command:
-
-```shell
-echo -n `sudo dmidecode -s system-uuid` > uuid_file.txt
-```
-
-The above command ensures the file does not end with whitespaces like LF and/or
-CR. The above command will not add any whitespaces. But the driver will handle
-situations where up to 2 additional bytes like CR and LF will be included in
-the file. Any more than that will make the driver fail to populate UUID in
-SMBIOS.

-

-## Utilizing a device driver
-
-The device driver must be enabled for your build.  There will be a CONFIG option
-in the Kconfig file in the directory that the driver is in (e.g.,
-``src/drivers/i2c/generic`` contains a Kconfig file; the option here is named
-CONFIG_DRIVERS_I2C_GENERIC).  The config option will need to be added to your
-mainboard's Kconfig file (e.g., ``src/mainboard/google/hatch/Kconfig``) in order
-to be compiled into your build.
-
-## Diving into the above example:
-
-Let's take a look at how the devicetree language corresponds to the generated
-ASL.
-
-First, note this:
-
-```
-    chip drivers/i2c/generic
-```
-
-This means that the device driver we're using has a corresponding structure,
-located at ``src/drivers/i2c/generic/chip.h``, named **struct
-drivers_i2c_generic_config** and it contains many properties you can specify to
-be included in the ACPI table.
-
-### hid
-
-```
-    register "hid" = ""ELAN0000""
-```
-
-This corresponds to **const char \*hid** in the struct.  In the ACPI ASL, it
-translates to:
-
-```
-    Name (_HID, "ELAN0000") // _HID: Hardware ID
-```
-
-under the device.  **This property is used to match the device to its driver
-during enumeration in the OS.**
-
-### desc
-
-```
-    register "desc" = ""ELAN Touchpad""
-```
-
-corresponds to **const char \*desc** and in ASL:
-
-```
-    Name (_DDN, "ELAN Touchpad") // _DDN: DOS Device Name
-```
-
-### irq
-
-It also adds the interrupt,
-
-```
-    Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, )
-    {
-        0x0000002D,
-    }
-```
-
-which comes from:
-
-```
-    register "irq" = "ACPI_IRQ_LEVEL_LOW(GPP_A21_IRQ)"
-```
-
-The IRQ settings control the "Trigger" and "Polarity" settings seen above (level
-means it is a level-triggered interrupt as opposed to
-edge-triggered; active low means the interrupt is triggered when the signal is
-low).
-
-Also note that the IRQ names are SoC-specific, and you will need to
-find the names in your SoC's header file.  The ACPI_* macros are defined in
-``src/arch/x86/include/acpi/acpi_device.h``.
-
-Using a GPIO as an IRQ requires that it is configured in coreboot correctly.
-This is often done in a mainboard-specific file named ``gpio.c``.
-
-AMD platforms don't have the ability to route GPIOs to the IO-APIC. Instead the
-GPIO controller needs to be used directly. You can do this by setting the
-`irq_gpio` register and using the `ACPI_GPIO_IRQ_X_X` macros.
-
-i.e.,
-```
-register "irq_gpio" = "ACPI_GPIO_IRQ_EDGE_LOW(GPIO_40)"
-```
-
-### detect
-
-The next register is:
-
-```
-    register "detect" = "1"
-```
-
-This flag tells the I2C driver that it should attempt to detect the presence of
-the device (using an I2C zero-byte write), and only generate a SSDT entry if the
-device is actually present. This alleviates the OS from having to determine if
-a device is present or not (ChromeOS/Linux) and prevents resource conflict/
-driver issues (Windows).
-
-Currently, the detect feature works and is hooked up for all I2C touchpads,
-and should be used any time a board has multiple touchpad options.
-I2C audio devices should also work without issue.
-
-Touchscreens can use this feature as well, but special care is needed to
-implement the proper power sequencing for the device to be detected. Generally,
-this means driving the enable GPIO high and holding the reset GPIO low in early
-GPIO init (bootblock/romstage), then releasing reset in ramstage. The first
-mainboards in the tree to implement this are google/skyrim and google/guybrush.
-This feature has also been used in downstream forks without issue for some time
-now on several other boards.
-
-### wake
-
-The last register is:
-
-```
-    register "wake" = "GPE0_DW0_21"
-```
-
-which indicates that the method of waking the system using the touchpad will be
-through a GPE, #21 associated with DW0, which is set up in devicetree.cb from
-this example.  The "21" indicates GPP_X21, where GPP_X is mapped onto DW0
-elsewhere in the devicetree.
-
-### device
-
-The last bit of the definition of that device includes:
-
-```
-    device i2c 15 on end
-```
-
-which means it's an I2C device, with 7-bit address 0x15, and the device is "on",
-meaning it will be exposed in the ACPI table.  The PCI device that the
-controller is located in determines which I2C bus the device is expected to be
-found on.  In this example, this is I2C bus 0.  This also determines the ACPI
-"Scope" that the device names and methods will live under, in this case
-"\_SB.PCI0.I2C0".
-
-## Wake sources
-
-The ACPI spec defines two methods to describe how a device can wake the system.
-Only one of these methods should be used, otherwise duplicate wake events will
-be generated.
-
-### Using GPEs as a wake source
-
-The `wake` property specified above is used to tell the ACPI subsystem that the
-device can use a GPE to wake the system. The OS can control whether to enable
-or disable the wake source by unmasking/masking off the GPE.
-
-The `GPIO` -> `GPE` mapping must be configured in firmware. On AMD platforms this is
-generally done by a mainboard specific `gpio.c` file that defines the GPIO
-using `PAD_SCI`. The `GPIO` -> `GPE` mapping is returned by the
-`soc_get_gpio_event_table` method that is defined in the SoC specific `gpio.c`
-file. On Intel platforms, you fill in the `pmc_gpe0_dw0`, `pmc_gpe0_dw1`, and
-`pmc_gpe0_dw2` fields in the devicetree to map 3 GPIO communities to `tier-1`
-GPEs (the rest are available as `tier-2` GPEs).
-
-Windows has a large caveat when using this method. If you use the `gpio_irq`
-property to define a `GpioInt` in the `_CRS`, and then use the `wake` property
-to define a `GPE`, Windows will
-[BSOD](https://github.com/MicrosoftDocs/windows-driver-docs/blob/staging/windows-driver-docs-pr/debugger/bug-check-0xa5--acpi-bios-error.md)
-complaining about an invalid ACPI configuration.
-> 0x1000D - A device used both GPE and GPIO interrupts, which is not supported.
-
-In order to avoid this error, you should use the `irq` property instead. AMD
-platforms don't support routing GPIOs to the IO-APIC, so this workaround isn't
-feasible. The other option is to use a wake capable GPIO as described below.
-
-### Using GPIO interrupts as a wake source
-
-The `ACPI_IRQ_WAKE_{EDGE,LEVEL}_{LOW,HIGH}` macros can be used when setting the
-`irq` or `gpio_irq` properties. This ends up setting `ExclusiveAndWake` or
-`SharedAndWake` on the `Interrupt` or `GpioInt` ACPI resource.
-
-This method has a few caveats:
-* On Intel and AMD platforms the IO-APIC can't wake the system. This means using
-  the `ACPI_IRQ_WAKE_*` macros with the `irq` property won't actually wake the
-  system. Instead you need to use the `gpio_irq` property, or a `GPE` as
-  described above.
-* The OS needs to know how to enable the `wake` bit on the GPIO. For linux this
-  means the platform specific GPIO controller driver must implement the
-  `irq_set_wake` callback. For AMD systems this wasn't
-  [implemented](https://github.com/torvalds/linux/commit/d62bd5ce12d79bcd6a6c3e4381daa7375dc21158)
-  until linux v5.15. If the controller doesn't define this callback, it's
-  possible for the firmware to manually set the `wake` bit on the GPIO. This is
-  often done in a mainboard-specific file named `gpio.c`. This is not
-  recommended because then it's not possible for the OS to disable the wake
-  source.
-* As of
-  [linux v6.0-rc5](https://github.com/torvalds/linux/releases/tag/v6.0-rc5),
-  the ACPI subsystem doesn't take the interrupt `wake` bit into account when
-  deciding on which power state to put the device in before suspending the
-  system. This means that if you define a power resource for a device via
-  `has_power_resource`, `enable_gpio`, etc, then the linux kernel will place the
-  device into D3Cold. i.e., power off the device.

-\_S0W indicates the deepest S0 sleep state this device can wake itself from,
-which in this case is `ACPI_DEVICE_SLEEP_D3_HOT`, representing _D3hot_.
-D3Hot means the `PR3` power resources are still on and the device is still
-responsive on the bus. For i2c devices this is generally the same state as `D0`.
-
-### \_PRW (Power Resources for Wake)
-\_PRW indicates the power resources and events required for wake.  There are no
-dependent power resources, but the GPE (GPE0_DW0_21) is mentioned here (0x15),
-as well as the deepest sleep state supporting waking the system (3), which is
-S3.

-### \_STA (Status)
-The \_STA method is generated automatically, and its values, 0xF, indicates the
-following:
-
-    Bit [0] – Set if the device is present.
-    Bit [1] – Set if the device is enabled and decoding its resources.
-    Bit [2] – Set if the device should be shown in the UI.
-    Bit [3] – Set if the device is functioning properly (cleared if device failed its diagnostics).
-
-### \_CRS (Current resource settings)
-The \_CRS method is generated automatically, as the driver knows it is an I2C
-controller, and so specifies how to configure the controller for proper
-operation with the touchpad.

-# Adding new devices to a device tree
-
-## Introduction
-
-ACPI exposes a platform-independent interface for operating systems to perform
-power management and other platform-level functions.  Some operating systems
-also use ACPI to enumerate devices that are not immediately discoverable, such
-as those behind I2C or SPI buses (in contrast to PCI).  This document discusses
-the way that coreboot uses the concept of a "device tree" to generate ACPI
-tables for usage by the operating system.
-
-## Devicetree and overridetree (if applicable)
-
-For mainboards that are organized around a "reference board" or "baseboard"
-model (see ``src/mainboard/google/octopus`` or ``hatch`` for examples), there is
-typically a devicetree.cb file that all boards share, and any differences for a
-specific board ("variant") are captured in the overridetree.cb file.  Any
-settings changed in the overridetree take precedence over those in the main
-devicetree.  Note, not all mainboards will have the devicetree/overridetree
-distinction, and may only have a devicetree.cb file.  Or you can always just
-write the ASL (ACPI Source Language) code yourself.
-
-### 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.
-
-## Device drivers
-
-Platform independent device drivers are hooked up via entries in a devicetree.
-See [Driver Devicetree Entries](../drivers/dt_entries.md) for more info.

-## Notes
-
- - **All fields that are left unspecified in the devicetree are initialized to
-   zero.**

-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.

-# 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])

-* fcode-utils: [Coverity Scan site][fcodeUtilsCoverity] ([build job][fcodeUtilsBuildJob])

-
-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

-### 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.

-00200000:007fffff bios
-00001000:001fffff me
-```
-
-### 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.
-
-```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.

-[flashrom] works out of the box since 0.9.2.
-Because of deficiency in vendor firmware, user needs to override the laptop
-warning as prompted. Once coreboot is in place there will be no further issue.
-
-### CPU microcode considerations
-
-By default, this board includes microcode updates for 5 families of Intel CPUs
-because of the wide variety of CPUs the board supports, directly or with an
-adapter. These take up a third of the total flash space leaving only 20kB free
-in the final cbfs image. It may be necessary to build a custom microcode update
-file by manually concatenating files in 3rdparty/intel-microcode/intel-ucode
-for only CPU models that the board will actually be run with.
-
-## Working
-
-- Slot 1 and Socket 370 CPUs and their L1/L2 caches
-- PS/2 keyboard with SeaBIOS (See [Known issues])
-- IDE hard drives
-- Ethernet (-LS, -L; Intel 82558)
-- SCSI (-LS, -S; Adaptec AIC7890)
-- USB
-- ISA add-on cards
-- PCI add-on cards
-- AGP graphics card
-- Floppy
-- Serial ports 1 and 2
-- Reboot
-- Soft off
-
-## Known issues
-
-- PS/2 keyboard may not be usable until Linux has completely booted.
-  With SeaBIOS as payload, setting keyboard initialization timeout to
-  500ms may fix the issue.
-
-- i440BX does not support 256Mbit RAM modules. If installed, coreboot
-  will attempt to initialize them at half their capacity anyway
-  whereas vendor firmware will not boot at all.
-
-- ECC memory can be used, but ECC support is still pending.
-
-- Termination is enabled for all SCSI ports (if equipped). Support to
-  disable termination is pending. Note that the SCSI-68 port is
-  always terminated, even with vendor firmware.
-
-## Untested

-flashrom supports this mainboard since commit c7e9a6e15153684672bbadd1fc6baed8247ba0f6.
-If you are using older versions of flashrom, below has to be done (with ACPI disabled!)
-before flashrom can detect the flash chip:
-
-```bash
-  #  rmmod w83781d
-  #  modprobe i2c-dev
-  #  i2cset 0 0x48 0x80 0x80
-```
-
-Upon power up, flash chip is inaccessible until flashrom has been run once.
-Since flashrom does not support reversing board enabling steps,
-once it detects the flash chip, there will be no write protection until
-the next power cycle.
-
-### CPU microcode considerations
-
-By default, this board includes microcode updates for 5 families of Intel CPUs
-because of the wide variety of CPUs the board supports, directly or with an
-adapter. These take up a third of the total flash space leaving only 20kB free
-in the final cbfs image. It may be necessary to build a custom microcode update
-file by manually concatenating files in 3rdparty/intel-microcode/intel-ucode
-for only CPU models that the board will actually be run with.
-
-## Working
-
-- Slot 1 and Socket 370 CPUs and their L1/L2 caches
-- PS/2 keyboard with SeaBIOS (See [Known issues])
-- IDE hard drives
-- USB
-- PCI add-on cards
-- AGP graphics cards
-- Serial ports 1 and 2
-- Reboot
-
-## Known issues
-
-- PS/2 keyboard may not be usable until Linux has completely booted. With SeaBIOS
-  as payload, setting keyboard initialization timeout to 2500ms may help.
-
-- The coreboot+SeaBIOS combination boots so quickly some IDE hard drives are not
-  yet ready by the time SeaBIOS attempts to boot from them.
-
-- i440BX does not support 256Mbit RAM modules. If installed, coreboot
-  will attempt to initialize them at half their capacity anyway
-  whereas vendor firmware will not boot at all.
-
-- ECC memory can be used, but ECC support is still pending.
-
-## Untested
-
-- Floppy
-- Parallel port
-- EDO memory
-- ECC memory
-- Infrared
-- PC speaker
-
-## Not working
-
-- ACPI (Support is currently [under gerrit review](https://review.coreboot.org/c/coreboot/+/41098))

-The flash chip is located between the blue SATA ports.
-
-The main SPI flash cannot be written internally because Asus disables BIOSWE and
-enables ``BLE/SMM_BWP`` flags in ``BIOS_CNTL`` for their latest bioses.
-To install coreboot for the first time, the flash chip must be removed and
-flashed with an external programmer; flashing in-circuit doesn't work.
-The flash chip is socketed, so it's easy to remove and reflash.
-
-## Working
-
-- All USB2 ports (mouse, keyboard and thumb drive)
-- USB3 ports on rear (Boots SystemRescue 6.0.3 off a Kingston DataTraveler G4 8GB)
-- Gigabit Ethernet (RTL8111F)
-- SATA3, SATA2 (all ports, hot-swap not tested)
-       (Blue SATA2)  (Blue SATA2)  (White SATA3)
-        port 5        port 3        port 1
-        port 6        port 4        port 2
-
-- CPU Temp sensors and hardware monitor (some values don't make sense)
-- Native and MRC memory initialization
-  (please see [Native raminit compatibility] and [MRC memory compatibility])
-
-- Integrated graphics with both libgfxinit and the Intel Video BIOS OpROM
-  (VGA/DVI-D/HDMI tested and working)
-- 16x PCIe GPU in PCIe-16x/4x slots (tested using nVidia Quadro 600 under SystemRescue 6.0.3
-  (Arch based))
-- Serial port
-- PCI slot
-  Rockwell HSF 56k PCI modem, Sound Blaster Live! CT4780 (cards detected, not function tested)
-  Promise SATA150 TX2plus (R/W OK to connected IDE hard drive, OpRom loaded, cannot boot from
-  SeaBIOS)
-- S3 suspend from Linux
-- 2-channel analog audio (WAV playback by mplayer via back panel line out port)
-- Windows 10 with libgfxinit high resolution framebuffer and VBT
-
-## Known issues
-
-- If you use MRC raminit, the NVRAM variable gfx_uma_size may be ignored as IGP's UMA could
-  be reconfigured by the blob.
-
-- If SeaBIOS is used for payload with libgfxinit, it must be brought in via coreboot's config.
-  Otherwise integrated graphics would fail with a black screen.
-
-- PCI POST card is not functional because the PCI bridge early init is not yet done.
-
-- The black PCIEX16_2 slot, although can physically fit an x16, only has physical contacts for
-  an x8, and is electrically an x4 only.
-
-## Untested
-
-- Wake-on-LAN
-- USB3 on header
-- TPM header
-- EHCI debugging (Debug port is on the 5-pin side of USB2_910 header)
-- HDMI and S/PDIF audio out
-
-## Not working
-
-- PS/2 keyboard or mouse
-- 4 and 6 channel analog audio out: Rear left and right audio is a muted
-  copy of front left and right audio, and the other two channels are silent.
-
-## Native (and MRC) raminit compatibility
-
-- OCZ OCZ3G1600LVAM 2x2GB kit works at DDR3-1066 instead of DDR3-1600.
-
-- GSkill F3-1600C9D-16GRSL 2x8GB SODIMM kit on adapter boots, but is highly unstable
-  with obvious pattern of bit errors during memtest86+ runs.
-
-- Samsung PC3-10600U 2x2GB kit works at full rated speed.
-
-- Kingston KTH9600B-4G 2x4GB kit works at full rated speed.
-
-## Extra onboard buttons
-
-The board has two onboard buttons, and each has a related LED nearby.
-What controls the LEDs and what the buttons control are unknown,
-therefore they currently do nothing under coreboot.
-
-- BIOS_FLBK
-  OEM firmware uses this button to facilitate a simple update mechanism
-  via a USB drive plugged into the bottom USB port of the USB/LAN stack.
-
-- MemOK!
-  OEM firmware uses this button for memory tuning related to overclocking.
