MRC settings are normally written to NVRAM at BS_DEV_ENUMERATE-EXIT.
If a platform requires MRC settings written to NVRAM later than
normal, select this item. This will cause the write to occur at
BS_OS_RESUME_CHECK-ENTRY.

bool
default y if MRC_WRITE_NV_LATE || BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES
default n
help
Instead of writing back MRC_CACHE training data back to the
MRC_CACHE right away, stash the data into cbmem. This data
will be written back later to MRC_CACHE. This is selected
for platforms which either do not support writes to SPI
flash in early stages
(BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES) or the platforms
that need to write back the MRC data in late ramstage boot
states (MRC_WRITE_NV_LATE).
config MRC_SAVE_HASH_IN_TPM
bool "Save a hash of the MRC_CACHE data in TPM NVRAM"
depends on VBOOT_STARTS_IN_BOOTBLOCK && TPM2 && !TPM1 && !VBOOT_MOCK_SECDATA
default y
help
Store a hash of the MRC_CACHE training data in a TPM NVRAM
space to ensure that it cannot be tampered with.
