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
board name, but it is not limited to that function.

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.

cf2978f4b6 drivers/vpd: Search VPD info at 0x0 first
We used to put SMBIOS header and other data before VPD.  That is not the
case anymore. New device will write the VPD starting at 0 instead of
0x600.  Search VPD at 0x0 to support this.

TEST=build and boot google/geralt. VPD is found both at 0 and at 0x600.

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]
  287 |         struct sm_object sm_obj_copy;
```

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.

773997c92d drivers/intel/touch: Avoid returning undefined pointer
Currently we may return an undefined pointer called
`none_driver_config` since stack variables are not by default
initialized to 0/NULL.
This also causes an issue when updating to a clang version 21.1.5 from
version 18.1.8, since it complains about this very issue.

returning NULL is fine, since the macros in this file actually depend on
it to figure out where to get the config from.

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.

74113f5d5e drivers/intel/fsp2_0: Add options to config VGA mode 12
This commit adds new Kconfig options and a code snippet to support
VGA mode 12 within the FSP (Firmware Support Package) 2.0. The
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.

Decrease the pixel clock from 4,400,560 Hz to 264,355 Hz to match the
actual panel timing specification. Also, the panel uses C-PHY interface,
so enable the `PANEL_FLAG_CPHY` flag accordingly.

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.

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.

a5252bd5b9 drivers/soundwire/cs35l56: Support Cirrus Logic CS35L56 Smart Amplifier Family
Add support for Class-D Smart Amplifiers: CS35L56, CS35L57 and CS35L63.

CS35L56 and CS35L57 are 18.5 V Class D Smart Amplifiers with Multi-Cell
Battery Boost.

CS35L63 is a PC Smart Amplifier with Speaker Protection and Audio
Enhancement Algorithms.

The driver was written based on the Datasheets for these parts and
generates the audio SSDT information for the amplifiers. Since all
three parts are part of the same family they all have similar SoundWire
settings.

The user can configure which part, SSID and Speaker ID is generated in
ACPI, as well as define each amplifier's Soundwire Unique ID and Link
ID.

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

These parts also support 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/cs35l56
	# SoundWire Link 2 ID 3
	register "desc" = ""Left Speaker Amp""
	register "part_id" = "MIPI_DEV_ID_CIRRUS_CS35L56"
	register "sub" = ""12345678""
	device generic 2.3 on end
end

Which produces the ACPI:

5f0225a7b5 drivers/intel/fsp2_0: Refactor for earlier graphics memory WC MTRR
Moves the MTRR setup for graphics memory (GMADR) from the
`soc_load_logo_by_coreboot()` function to `do_silicon_init()`. This
refactors the logic into a new helper function,
`soc_mark_gfx_memory()`, which acquires a temporary Write-Combine
(WC) MTRR.

The MTRR is now configured earlier in the silicon initialization
process, making the setup and cleanup independent of the
`soc_load_logo_by_coreboot()` function itself.

This improves FSP-S performance and ensures the MTRR is correctly
managed within the silicon initialization flow which was earlier
missed when platform selects `USE_COREBOOT_FOR_BMP_RENDERING` aka
rendering the BMP logo using coreboot driver and not using FSP driver
logic.

The cleanup of the MTRR is also moved to `do_silicon_init()` to pair
with the earlier setup.

TEST=Successfully boot to OS on google/fatcat using coreboot for logo
rendering.

8f09629fb1 spi_flash: Fix initialization of flags field in lb_spi_flash
Commit 8dec5fcaf8 ("drivers/spi: Add 4-byte address mode flag to
lb_spi_flash") split the existing 32-bit `erase_cmd` field into multiple
fields. The new `flags` field thus created is used to pass information
about whether the flash is in 4-byte address mode.

Unfortunately, we forgot to initialize the new fields in the case that
the flash is not in 4-byte address mode. This means it can have any
arbitrary value, including values where the new flag bit is accidentally
set (causing flash access errors in the payload).

This patch fixes the problem and tries to prevent further issues with
field changes in the future by explicitly zeroing the entire coreboot
table structure before starting to fill in the values.

2c8d157ea4 {drivers, soc/qualcomm/common}: Add configurable delay for UART bitbang
This commit introduces a new Kconfig option, UART_BITBANG_TX_DELAY_MS,
to make the UART TX pin stabilization delay configurable.

A default 5ms (CONFIG_UART_BITBANG_TX_DELAY_MS) delay is added in
uart_init() after the TX pin is set high. This addresses an issue
where the initial character sent by the UART could be corrupted due
to the pin not being stable. The delay ensures the line state is
properly established before data transmission begins.

This was found to resolve early boot console corruption on some boards.
The issue is likely a race condition where the first character starts
transmitting before the GPIO output is fully stabilized.

TEST=Able to build and boot google/zombie w/o any junk characters in
AP firmware log.

9a8ba5b39a {lib, drivers/intel}: Move BMP rendering logic out of SoC code
This patch refactors the BMP rendering logic, moving it from
drivers/intel/fsp2_0 to src/lib. This centralizes the code
responsible for rendering BMP images to the framebuffer.

Key changes:
- Move BMP rendering functions (e.g., calculate_logo_coordinates,
  copy_logo_to_framebuffer) and their dependencies to
  src/lib/render_bmp.c and src/lib/render_bmp.h.
- Decouple BMP definitions from UEFI headers by introducing new
  coreboot-specific structures for BMP images and BLT pixels.
- Consolidate bootsplash-related declarations into bootsplash.h,
  including new `fw_splash_vertical_alignment`,
  `fw_splash_horizontal_alignment`, and `struct logo_config`.
- Update `soc_load_logo_by_coreboot` to use the new common
  `load_and_render_logo_to_framebuffer` function and `struct
  logo_config` for rendering.
- Relocate `release_logo` to `src/lib/render_bmp.c` for better
  module structure.
- Update `src/lib/Makefile.mk` to include the new render_bmp.c.

This refactoring improves code organization and reusability, making
BMP rendering accessible without tight coupling to Intel-specific
driver code.

5171098814 drivers/qemu/bochs: Allow building for non-x86 architectures
The Bochs display driver uses port I/O functions to initialize the VGA
device, so it could only have been built on x86 architectures so far,
but its supported devices can be used just fine on others on the QEMU
side as long as the emulated platform supports PCI. A previous commit
adds port I/O functions for more including ARM* and RISC-V, which should
enable this driver to be successfully built and used on these as well.

Allow the Bochs display driver to be built for non-x86 QEMU boards by
changing the Kconfig dependencies. Make VGA text framebuffer support
depend on x86, because it isn't usable at the standard 0xB8000 address
on other architectures. Add a dependency on PCI since this is a PCI
device and vexpress-a9 (qemu-armv7) doesn't have the (emulated) hardware
for PCI.

8dec5fcaf8 drivers/spi: Add 4-byte address mode flag to lb_spi_flash
Adds a new flags field to the lb_spi_flash coreboot table to indicate
if the SPI flash is operating in 4-byte address mode.

This allows payloads to query the current address mode directly from the
coreboot table, preventing redundant checks or re-enforcement of the
mode. The flag is set based on the
CONFIG_SPI_FLASH_FORCE_4_BYTE_ADDR_MODE configuration.

Important: `erase_cmd` was reduced from uint32_t to uint8_t.
Only the least significant byte was ever relevant, so this change
ensures accurate type representation, maintains backward compatibility
with existing coreboot table structures, and frees up space.

a01c368a8a drivers/spi: Refactor 4-byte addressing mode handling in SPI flash
This commit refactors the logic for entering and exiting 4-byte
addressing mode in the SPI flash driver.

Changes include:
 - Renaming SPI_FLASH_EXIT_4BYTE_STAGE to SPI_FIRST_STAGE to better
   reflect its broader applicability to initial boot stages.
 - Applying SPI_FIRST_STAGE to both the force 4-byte address mode
   and exit 4-byte address mode configurations, ensuring these
   operations are only attempted during the appropriate early boot
   phases.
 - Renaming CMD_FORCE_4BYTE_ADDR_MODE to CMD_ENTER_4BYTE_ADDR_MODE for
   consistency and clearer semantics, as 0xb7 is typically used to enter
   this mode.

5568bee055 drivers/spi: Support forced 4-byte address mode via 0xB7 command
Many high-capacity SPI flashes (e.g., >16MB) default to 3-byte
addressing and require a specific command to enter 4-byte address mode.

This commit introduces support for sending the
CMD_FORCE_4BYTE_ADDR_MODE (0xB7) command during flash probing. When
Kconfig option `SPI_FLASH_FORCE_4_BYTE_ADDR_MODE` is enabled, this
ensures the flash chip is immediately switched to 4-byte addressing
after power-on.

This addresses issues with flashes like GigaDevice (GD25LQ128D) and
Winbond (W25Q256JWxx) that mandate this command for proper 4-byte
addressing. The new command definition is in `spi_flash_internal.h`.

2a09db3c29 drivers/intel: Refactor logo rendering with helper functions
This commit refactors the `soc_load_logo_by_coreboot()` function by
extracting common logo rendering logic into a new helper function:
`render_logo_to_framebuffer()`.

The `render_logo_to_framebuffer()` helper is responsible for:
- Loading the BMP image (by type).
- Checking the image size.
- Converting the BMP to GOP BLT format.
- Calculating the appropriate logo coordinates based on vertical
  or horizontal alignment, considering panel orientation for the
  footer logo.
- Copying the logo data to the framebuffer.
- Releasing the allocated logo buffer.

This refactoring significantly reduces code duplication within
`soc_load_logo_by_coreboot()`, making it more concise and readable.
It also centralizes the logo rendering process, improving
maintainability and simplifying future modifications.

The `soc_load_logo_by_coreboot()` function now focuses on
higher-level orchestration: graphics info initialization, MTRR
setup, panel orientation adjustment, and sequential calls to
`render_logo_to_framebuffer()` for the main and optional footer logos.
Error handling for MTRR and logo rendering failures is streamlined
with a `cleanup` goto label.
