Enable ChromeOS specific features like the GPIO sub table in
the coreboot table. NOTE: Enabling this option on an unsupported
board will most likely break your build.

This option is needed to add ACPI regulatory domain methods
config CHROMEOS_DISABLE_PLATFORM_HIERARCHY_ON_RESUME
bool
default y
depends on TPM2 && RESUME_PATH_SAME_AS_BOOT
help
Disable the platform heirarchy on resume path if the firmware
is involved in resume. The hierarchy is disabled prior to jumping
to the OS. Note that this option is sepcific to TPM2 boards.
This option is auto selected if CHROMEOS because it matches with
vboot_reference model which disables the platform hierarchy in
the boot loader. However, those operations need to be symmetric
on normal boot as well as resume and coreboot is only involved
in the resume piece w.r.t. the platform hierarchy.
config CHROMEOS_USE_EC_WATCHDOG_FLAG
bool
default n
help
Use the AP watchdog flag stored in EC.
config CHROMEOS_DSM_CALIB
bool
default n
help
On some boards, there are calibrated parameters for Dynamic Speaker Management(DSM)
stored in VPD. Enable this config to read and parse these VPD values and write them
to ACPI DSD table in device driver. These parameters will be applied by kernel driver
through device property at boot.
config CHROMEOS_DSM_PARAM_FILE_NAME
bool
default n
help
On some boards, there are different dsm parameter files for Dynamic Speaker
Management (DSM). Enable this config to assign dsm parameters file name in ACPI
SSDT table. Kernel driver uses this to load the DSM parameter file.
config CHROMEOS_CSE_BOARD_RESET_OVERRIDE
bool
default n
depends on SOC_INTEL_CSE_LITE_SKU
help
On some boards that run old firmware version in cr50, Embedded Controller (EC) needs
to trigger the cold reset of Application Processor (AP) when CSE jumps from RO to RW
so that cr50 resets the TPM state. This is required on boards where the cr50 firmware
does not understand the new cr50 strap config (applicable only to boards using strap
config 0xe). Enabling this config will help to override the default global reset.
config CHROMEOS_DRAM_PART_NUMBER_IN_CBI
def_bool n

help
Some boards declare the DRAM part number in the CBI instead of the SPD. This option
allows those boards to declare that their DRAM part number is stored in the CBI.
