1dc3e45f7c mipi: Support passing user data to mipi_cmd_func_t
The mipi_cmd_func_t callback for mipi_panel_parse_init_commands()
currently doesn't support passing additional data for storing context.
Therefore user code would need to store any extra data in global
variables. For example, in the upcoming DSI dual channel support for
MediaTek platforms, the callback needs to know whether the MIPI panel
supports dual channel or not. To support that use case, pass an extra
`user_data` argument to mipi_cmd_func_t.

d32a372846 drivers/smmstore: Increase default size of store to 512KB
The previous default size of 256KB provided for only 64KB of actual
space for EFI variables, and after accounting for fragmentation, did
not provide enough free space for applying updates, such as for the
UEFI revocation database (DBX). Increasing it to 512KB allows for
192KB space for variables, and allows the UEFI DBX to be updated
properly via fwupd.

TEST=build/boot google/drobit, verify UEFI DBX able to be successfully
updated via fwupd.

ac5c57d24a drivers/tpm/ppi: Fix generated ACPI
The SSDT contains:
    CreateByteField (PPOP, Local0, TPPF)

However, CreateByteField requires the source argument to be
(Buffer | String | Integer).  PPOP is an OperationRegion, so
iasl correctly reports:

    Error 6058 - Invalid type ([Region] found)

Per ACPI spec, OperationRegions must use CreateField rather than
CreateByteField. Replace the AML emission with:

    CreateField (PPOP, Local0 * 8, 8, TPPF)

This reads one byte at an arbitrary offset inside the PPI
OpRegion and is fully standards-compliant. This isn't a
functional change, just "correct".

Test=boot starbook_mtl, verify iasl can decompile and recompile
SSDT and TPM is still operational.

e6a8143d8b drivers/intel/touch: Add support for new Intel touch I2C _DSD entries
This update enhances the Intel touch driver by incorporating support for
newly added _DSD entries specific to I2C devices. The enhancements
include:

- Adding new entries in the I2C _DSD to enable configurations for
  maximum frame size and interrupt delay settings.
- Introducing device-specific interrupt delay settings tailored for
  Hynitron devices.

These changes ensure improved configurability and performance tuning for
supported devices. It is crucial to use this update with an operating
system that includes corresponding changes for this new support.

ATTENTION: This change requires a THC driver fix. If the OS does not
have the driver fix, please use LPSS I2C or disable the touchscreen
and touchpad. For instance, on the Google Fatcat board, use the
following CBI fw_config options:
TOUCHSCREEN field: TOUCHSCREEN_LPSS_I2C or TOUCHSCREEN_NONE
TOUCHPAD field: TOUCHPAD_LPSS_I2C or TOUCHPAD_NONE

23b00a06da drivers/intel/gma: Fix brightness handling with valid-cache logic
The existing brightness level fallback logic duplicated the default
backlight value by hardcoding BRLV to 100% (0x64). This caused divergence
whenever a platform defined a different default brightness through BRIG[0].

This change removes the duplicated default and replaces it with a cached
brightness mechanism using BRVA (valid flag) and BRLV (cached level).
The firmware now:

 - Caches the last brightness level exposed to the OS.
 - Uses the cached level during early boot/resume when the OpRegion
   (BCLM/BCLV) is not yet initialized.
 - Falls back to BRIG[0] only when no cached brightness exists.
 - Preserves the existing replay-detection logic to keep firmware and OS
   brightness state aligned once the graphics driver is active.

This ensures consistent brightness reporting, avoids incorrect 0% fallback
values, and respects board-specific BRIG defaults.

No functional changes occur once the graphics driver has initialized the
OpRegion; the improvement only affects early boot/resume behavior and
eliminates duplicated platform policy.

109672a9a9 drivers/intel/gma: Guard legacy brightness fallback
When BOX3.XBCM fails we currently fall back to LEGA.XBCM, which writes
directly to the IGD PWM registers. During S3 resume those registers are
still reset by the graphics driver, so AML stores a zero duty cycle and
the panel stays dark. This leads to having some other event needed to
wake the panel (i.e. key press).

Only invoke the legacy path after BCLM is initialized, matching when the
driver has reprogrammed the PWM registers and preventing firmware from
touching them while the driver is still restoring them.

Test=Enter and exit S3 on starbook_mtl, verify that the display turns on and stays on, instead of on -> off -> on.

ddb3f0b17f drivers/hwid_dmi: Populate SMBIOS product name from CBFS hwid file
Add driver to read 'hwid' file from CBFS and use it for SMBIOS product
name. Processes the ChromeOS-format HWID string by removing prefix
after colon, trimming whitespace, and extracting base name before
any hyphen/space. Returned string is normalized to have the first
character/letter capitalized, and the rest lower case. If no HWID file
is found in CBFS, the fallback is CONFIG_MAINBOARD_SMBIOS_PRODUCT_NAME.

This driver is intended to allow ChromeOS devices running upstream
coreboot to persist their board's unique HWID and use it as the SMBIOS

TEST=tested in MrChromebox downstream. Multiple devices which use the
same ChromeOS board but differ in HWID can use the same firmware image
and still be properly identified.

e9c47bf99e drivers/intel/fsp2_0: Add 1-bpp monochrome option for VGA mode 12
Add a new Kconfig option, FSP_VGA_MODE12_MONOCHROME, to allow the
system to use a 1-bit-per-pixel (1bpp) planar VGA buffer during FSP
initialization instead of the standard 4bpp buffer. This is useful
in romstage where every byte is critical.

When this option is enabled, the FSP is expected to handle the
internal replication of the 1bpp data across the other three
color planes to render the monochrome image.

Key changes:
- Introduce FSP_VGA_MODE12_MONOCHROME Kconfig option.
- Automatically select FSP_VGA_MODE12 when the monochrome option is
used.
- Set FSP_VGA_MODE12_BPP to 0x1 when FSP_VGA_MODE12_MONOCHROME is
selected.

91594f4894 drivers/option/cfr.c: Replace memcpy() to avoid uninitialized object
When updating clang to version 21.1.5, we now get the following error
when compiling the CFR code.
```
src/drivers/option/cfr.c:287:19: error: default initialization of an
      object of type 'struct sm_object' with const member leaves the object uninitialized
      [-Werror,-Wdefault-const-init-field-unsafe]

In this specific case its actually not an issue, but initialize the
variable from the start to avoid the error and arguably make the code
easier to read.

c197643d44 drivers/intel/gma/acpi: Add power management methods for GFX0
Add ACPI power state methods (_PS0, _PS3, _S0W, _S3D) to the GFX0
device definition to fix VIDEO_TDR_FAILURE 0x116 errors when
resuming from S3 sleep under Windows on modern Intel platforms
(TGL and newer).

Windows requires these methods to properly manage GPU power states
during sleep/resume cycles. Without them, Windows cannot determine
the correct power state transitions, leading to display driver
timeouts on resume.

The methods are implemented as no-ops since integrated graphics
power is managed by the platform, but Windows needs the method
definitions to properly initialize and restore the GPU after S3
resume.

TEST=build/boot starlabs/starlite_adl, verify S3 resume from
Windows works properly without a VIDEO_TDR_FAILURE BSOD.

returning NULL is fine, since the macros in this file actually depend on

786ac14d48 drivers/option/cfr: Add optional override table for default values
Add a mechanism for mainboards to override default values of CFR
objects defined in SoC or common code without duplicating object
metadata.

Mainboards can now declare a simple override table mapping option
names to new default values:

  const struct cfr_default_override mb_cfr_overrides[] = {
      CFR_OVERRIDE_BOOL("s0ix_enable", false),
      CFR_OVERRIDE_ENUM("pciexp_aspm", ASPM_DISABLE),
      CFR_OVERRIDE_END
  };

The CFR backend checks this table when writing options and uses the
override value if one exists. All other metadata (name, help text,
enum values, flags) comes from the original object.

changes allow platforms to select VGA mode 12 and configure it.

The key features are:
- Introduces `FSP_VGA_MODE12` to enable VGA mode 12 support.
- A new `FSP_VGA_MODE12_BPP` option defines the bits per pixel,
  defaulting to 4 for color mode.
- A bitmap buffer is allocated on the stack and supplied to FSP
  based on the configured bits per pixel.

f1c973bbff drivers/soundwire/cs42l43: Support Cirrus Logic CS42L43 codec
CS42L43 is a PC Codec with headphone and class D speaker drivers.

The driver was written based on the datasheet for CS42L43 part and
generates the audio SSDT information.

CS42L43 supports DisCo Version v2.1, but coreboot currently only
supports DisCo v1.0, so ACPI is only generated based on DisCo v1.0.

CS42L43 also supports the SDCA v1.0 Specification (from DisCo v2.1)
is also not currently supported by coreboot, therefore SDCA ACPI
properties are also not generated.

This is currently only tested using QEMU using example configuration:

chip drivers/soundwire/cs42l43
	# SoundWire Link 0 ID 1
	register "desc" = ""CODEC""
	register "sub" = ""1337""
	device generic 0.1 on end
end

Which produces the ACPI:

    Name (_DDN, "CODEC")  // _DDN: DOS Device Name

85d7a1c85f drivers/ipmi: add Block Transfer (BT) interface
Unlike already implemented Keyboard Controller Style (KCS) interface
Block Transfer interface is not byte-oriented and implies that device is
capable of buffering a command before processing it.  Another difference
is that polling can be replaced with interrupts, though this isn't used
by this implementation.

More details can be found in "Intelligent Platform Management Interface
Specification", v2.0, Rev. 1.1:
https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/ipmi-intelligent-platform-mgt-interface-spec-2nd-gen-v2-0-spec-update.pdf

This was initially tested on Talos II (OpenPower platform) by Raptor
Computing Systems.  Later versions were tested using QEMU and ipmi_sim
from OpenIPMI project as well as QEMU's builtin BMC simulator.

EFI_MP_SERVICES_PROTOCOL.GetProcessorInfo() in the Platform
Initialization Specification 1.7. If bit 24 (CPU_V2_EXTENDED_TOPOLOGY)
is set in ProcessorId, GetProcessorInfo() must populate the
EFI_CPU_PHYSICAL_LOCATION2 data structure.

TEST=FSP using PI 1.7 GetProcessorInfo() is able to retrieve the
     information instead of receiving an EFI_NOT_FOUND error.

f1708cf21a drivers/intel/touch: Enhance Intel touch driver for new devices
Enhancements have been made to the Intel touch driver, including support
for Google touchscreen devices, ELAN9006 and ELAN6918. The update
also includes device-specific configuration changes for both I2C and SPI
interfaces.

Key improvements include:
- Google Touchscreen support integration for ELAN9006 (SPI) and ELAN6918
  (I2C).
- Specification of recommended connection speeds for supported devices.
- Removal of an unnecessary 100ms delay in the SPI _RST method.
- Addition of a function to map the System on Chip's (SoC) I2C speed
  frequency.
- Improved device-specific connection speed settings for both I2C and
  SPI interfaces.

These changes aim to improve the driver’s compatibility and efficiency
when interacting with the newly supported devices.

BUG=none

TEST=Test the updated driver on devices using ELAN9006 and ELAN6918 to
verify improved responsiveness and correct device initialization.
Confirm that connection speeds are set as recommended and check the
absence of the previously unnecessary delay in SPI operations from the
SSDT.

23419df34c drivers/intel/fsp2_0: Implement API to retrieve DIMM info
This patch extracts the implementation responsible for retrieving DIMM
information from the FSP HOBs and centralizes it within the common FSP
driver code.

This ensures that each SoC layer does not duplicate the logic for
parsing memory-related data. The primary goal is to rely on the
common FSP driver code for retrieving memory information.

The only SoC-specific implementation that remains is limited to
handling dependencies related to FSP UPD or header differences across
SoC generations.

TEST=Able to build and boot google/kinmen. Verify the memory related
information is proper as part of the SMBIOS table.
