+# 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:
+
+```
+    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".
+
+## Other auto-generated names
+
+(see [ACPI specification
+6.3](https://uefi.org/sites/default/files/resources/ACPI_6_3_final_Jan30.pdf)
+for more details on ACPI methods)
+
+### _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
+{
+    I2cSerialBusV2 (0x0015, ControllerInitiated, 400000,
+                    AddressingMode7Bit, "\\_SB.PCI0.I2C0",
+                    0x00, ResourceConsumer, , Exclusive, )
+```
+
+## Notes
+
+ - **All fields that are left unspecified in the devicetree are initialized to
+   zero.**
+ - **All devices in devicetrees end up in the SSDT table, and are generated in
+   coreboot's ramstage**

 Functions whose return value is the actual result of a computation,
 rather than an indication of whether the computation succeeded, are not
 subject to this rule. Generally they indicate failure by returning some
 out-of-range result. Typical examples would be functions that return
-pointers; they use NULL to report failure.
-
-Error handling, assertions and die()
------------------------------
-
-As firmware, coreboot has no means to let the user interactively fix things when
-something goes wrong. We either succeed to boot or the device becomes a brick
-that must be recovered through complicated external means (e.g. a flash
-programmer). Therefore, coreboot code should strive to continue booting
-wherever possible.
-
-In most cases, errors should be handled by logging a message of at least
-`BIOS_ERR` level, returning out of the function stack for the failed feature,
-and then continuing execution. For example, if a function reading the EDID of an
-eDP display panel encounters an I2C error, it should print a "cannot read EDID"
-message and return an error code. The calling display initialization function
-knows that without the EDID there is no way to initialize the display correctly,
-so it will also immediately return with an error code without running its
-remaining code that would initialize the SoC's display controller. Exeuction
-returns further up the function stack to the mainboard initialization code
-which continues booting despite the failed display initialization, since
-display functionality is non-essential to the system. (Code is encouraged but
-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()`).

-# 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
-

-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

-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

-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.

-for more details on ACPI methods)
-
-### _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_.
-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.
-
-```
-Name (_CRS, ResourceTemplate ()  // _CRS: Current Resource Settings
-{
-    I2cSerialBusV2 (0x0015, ControllerInitiated, 400000,
-                    AddressingMode7Bit, "\\_SB.PCI0.I2C0",
-                    0x00, ResourceConsumer, , Exclusive, )
-```
-
-## Notes
-
- - **All device driver entries in devicetrees end up in the SSDT table, and are
-   generated in coreboot's ramstage**
-   (The lone exception to this rule is i2c touchpads with the 'detect' flag set;
-    in this case, devices not present will not be added to the SSDT)

-# 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.

-[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.

-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

-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)

-- 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.

-
-This page is about the notebook [HP EliteBook 2170p].
-
-## Release status
-
-HP EliteBook 2170p was released in 2012 and is now end of life.
-It can be bought from a secondhand market like Taobao or eBay.
-
-## Required proprietary blobs
-
-The following blobs are required to operate the hardware:
-1. EC firmware
-2. Intel ME firmware
-
-EC firmware can be retrieved from the HP firmware update image, or the firmware
-backup of the laptop. EC Firmware is part of the coreboot build process.
-The guide on extracting EC firmware and using it to build coreboot is in
-document [HP Laptops with KBC1126 Embedded Controller](hp_kbc1126_laptops).
-
-Intel ME firmware is in the flash chip. It is not needed when building coreboot.
-
-## Programming
-
-The flash chip is located between the memory slots, WWAN card and CPU,
-covered by the base enclosure, which needs to be removed according to
-the [Maintenance and Service Guide] to access the flash chip. Unlike
-other variants, the flash chip on 2170p is socketed, so it can be taken
-off and operated with an external programmer.
-
-Pin 1 of the flash chip is at the side near the CPU.
-

 ```
 
 ### Internal programming
 
 The SPI flash can be accessed using [flashrom].
-```console
-$ flashrom -p internal -c MX25L6406E/MX25L6408E -w coreboot.rom
-```
-
-After shorting the FDO jumper you gain access to the full flash, but you
-still cannot write in the bios region due to SPI protected ranges.
-
-**Position of FDO jumper close to the IO and second fan connector**
-![][compaq_8200_jumper]
-
-[compaq_8200_jumper]: compaq_8200_sff_jumper.jpg
-
-To write to the bios region you can use an [IFD Hack] originally developed
-for MacBooks, but with modified values described in this guide.
-You should read both guides before attempting the procedure.
-
-Since you can still write in the flash descriptor, you can shrink
-the ME and then move the bios region into where the ME originally was.
-coreboot does not by default restrict writing to any part of the flash, so
-you will first flash a small coreboot build and after it boots, flash
-the full one.
-
-The temporary flash layout with the neutered ME firmware should look like this:
-```
-00000000:00000fff fd
-00023000:001fffff bios
-00003000:00022fff me
-00001000:00002fff gbe
-00200000:007fffff pd
-```
-
-It is very important to use these exact numbers or you will need to fix it
-using external flashing, but you should already be familiar with the risks
-if you got this far.
-
-The temporary ROM chip size to set in menuconfig is 2 MB but the default
-CBFS size is too large for that, you can use up to about 0x1D0000.
-
-When building both the temporary and the permanent installation, don't forget
-to also add the gigabit ethernet configuration when adding the flash descriptor
-and ME firmware.
-
-You can pad the ROM to the required 8MB with zeros using:
-```console
-$ dd if=/dev/zero of=6M.bin bs=1024 count=6144
-$ cat coreboot.rom 6M.bin > coreboot8.rom
-```
-
-If you want to continue using the neutered ME firmware use this flash layout
-for stage 2:
-```
-00000000:00000fff fd
-00023000:007fffff bios
-00003000:00022fff me
-00001000:00002fff gbe
-```
-
-If you want to use the original ME firmware use the original flash layout.
-
-More about flashing internally and getting the flash layout [here](../../tutorial/flashing_firmware/index.md).

-Internal programming is possible. Shorting the Flash Descriptor Override
-(FDO) jumper bypasses all write protections.
-
-### External programming
-
-Remove the lid. The flash chip can be found on the edge opposite to the CPU.
-There is a spot for a "ROM RCVRY" header next to the flash chip but it is
-unpopulated. If you don't feel like using a clip, you can easily solder
-a standard pin header there yourself and use it for programming.
-
-Programming powers some parts of the board. Programming when

-## Release status
-
-HP EliteBook 820 G2 was released in 2015 and is now end of life.
-It can be bought from a secondhand market like Taobao or eBay.
-
-## Required proprietary blobs
-
-The following blobs are required to operate the hardware:
-
-1. EC firmware
-2. Intel ME firmware
-3. Broadwell mrc.bin and refcode.elf
-
-HP EliteBook 820 G2 uses SMSC MEC1324 as its embedded controller.
-The EC firmware is stored in the flash chip, but we don't need to touch it
-or use it in the coreboot build process.
-
-Intel ME firmware is in the flash chip. It is not needed when building coreboot.
-
-The Broadwell memory reference code binary and reference code blob is needed
-when building coreboot. Read the document [Blobs used in Intel Broadwell boards]
-on how to get these blobs.
-
-## Programming
-
-Before flashing, remove the battery and the hard drive cover according to the
-[Maintenance and Service Guide] of this laptop.
-
-HP EliteBook 820 G2 has two flash chips, a 16MiB system flash, and a 2MiB
-private flash. To install coreboot, we need to program both flash chips.
-Read [HP Sure Start] for detailed information.
-
-![HP EliteBook 820 G2 flash chip](elitebook_820_g2_flash.jpg)
-
-To access the system flash, we need to connect the AC adapter to the machine,
-then clip on the flash chip with an SOIC-8 clip. An [STM32-based flash programmer]
-made with an STM32 development board is tested to work.
-
-To access the private flash chip, we can use a ch341a based flash programmer and
-flash the chip with the AC adapter disconnected.
-
-To flash coreboot on a board running OME firmware, create a backup for both flash
-chips, then do the following:
-
-1. Erase the private flash to disable the IFD protection
-2. Modify the IFD to shrink the BIOS region, so that we can put the firmware outside
-   the protected flash region
-
-To erase the private flash chip, attach it with the flash programmer via the SOIC-8 clip,
-then run:
-
-    flashrom -p <programmer> --erase
-
-To modify the IFD, write the following flash layout to a file:
-
-    00000000:00000fff fd
-    00001000:00002fff gbe
-    00003000:005fffff me
-    00600000:00bfffff bios
-    00eb5000:00ffffff pd
-
-Suppose the above layout file is ``layout.txt`` and the origin content of the system flash
-is in ``factory-sys.rom``, run:
-
-    ifdtool -n layout.txt factory-sys.rom
-
-Then a flash image with a new IFD will be in ``factory-sys.rom.new``.
-
-Flash the IFD of the system flash:
-
-    flashrom -p <programmer> --ifd -i fd -w factory-sys.rom.new
-
-Then flash the coreboot image:
-
-    # first extend the 12M coreboot.rom to 16M
-    fallocate -l 16M build/coreboot.rom
-    flashrom -p <programmer> --ifd -i bios -w build/coreboot.rom
-
-After coreboot is installed, the coreboot firmware can be updated with internal flashing:
-
-    flashrom -p internal --ifd -i bios --noverify-all -w build/coreboot.rom
-
-## Debugging
-
-The board can be debugged with EHCI debug. The EHCI debug port is the USB port on the left.

-## Status
-
-### Working
-
-- Sandy Bridge and Ivy Bridge CPUs (tested: i5-2500, Pentium G2120)
-- Native RAM initialization with four DIMMs
-- Integrated GPU with libgfxinit
-- PCIe graphics in the PEG slot
-- Additional PCIe slots
-- PCI slot
-- All rear (4x) and internal (8x) USB2 ports
-- Rear USB3 ports (2x)
-- All four internal SATA ports (two 6 Gb/s, two 3 Gb/s)
-- Two rear eSATA connectors (3 Gb/s)
-- SATA at 6 Gb/s
-- Gigabit Ethernet
-- SeaBIOS 1.16.1 + libgfxinit (legacy VGA) to boot slackware64 (Linux 5.15)
-- SeaBIOS 1.16.1 + extracted VGA BIOS to boot Windows 10 (21H2)
-- edk2 UefiPayload (uefipayload_202207) + libgfxinit (high-res) to boot:
-    - slackware64 (Linux 5.15)
-    - Windows 10 (22H2)
-- External in-circuit flashing with flashrom-1.2 and a Raspberry Pi 1
-- Poweroff
-- Resume from S3
-- Console output on the serial port
-
-### Not working
-
-- Automatic fan control. One can still use OS-based fan control programs,
-  such as fancontrol on Linux or SpeedFan on Windows.
-- Windows 10 booted from SeaBIOS + libgfxinit (high-res). The installation
-  works, but once Windows Update installs drivers, it crashes and enters a
-  bootloop.
-
-### Untested
-
-- Firewire (LSI L-FW3227-100)
-- EHCI debug

-
-The flash is divided into the following regions, as obtained with
-`ifdtool -f rom.layout backup.rom`:
-
-    00000000:00000fff fd
-    00580000:007fffff bios
-    00003000:0057ffff me
-    00001000:00002fff gbe
-
-Unfortunately the SPI interface to the chip is locked down by the vendor
-firmware. The BIOS Lock Enable (BLE) bit of the `BIOS_CNTL` register, part of
-the PCI configuration space of the LPC Interface Bridge, is set.
-
-It is possible to program the chip is to attach an external programmer
-with an SOIC-8 clip.
-
-```eval_rst
-Another way is to boot the vendor firmware in UEFI mode and exploit the
-unpatched S3 Boot Script vulnerability. See this page for a similar procedure:
-:doc:`../lenovo/ivb_internal_flashing`.
-```
-
-On this specific board it is possible to prevent the BLE bit from being set
-when it resumes from S3. One entry in the S3 Boot Script must be modified,
-e.g. with a patched version of [CHIPSEC](https://github.com/chipsec/chipsec)
-that supports this specific type of S3 Boot Script, for example from strobo5:
-
-    $ git clone -b headerless https://github.com/strobo5/chipsec.git
-    $ cd chipsec
-    $ python setup.py build_ext -i
-    $ sudo python chipsec_main.py -m tools.uefi.s3script_modify -a replace_op,mmio_wr,0xe00f80dc,0x00,1
-
-The boot script contains an entry that writes 0x02 to memory at address
-0xe00f80dc. This address points at the PCIe configuration register at offset
-0xdc for the PCIe device 0:1f.0, which is the BIOS Control Register of the LPC
-Interface Bridge [0][1]. The value 0x02 sets the BLE bit, and the modification
-prevents this by making it write a 0 instead.
-
-```eval_rst
-After suspending and resuming the board, the BIOS region can be flashed with
-a coreboot image, e.g. using flashrom. Note that the ME region is not readable,
-so the `--noverify-all` flag is necessary. Please refer to the
-:doc:`../../tutorial/flashing_firmware/index`.
-```
-
-## Hardware monitoring and fan control
-
-Currently there is no automatic, OS-independent fan control.
-
-## 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.
-
-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
-                 +---+---+
