the coreboot table. NOTE: Enabling this option on an unsupported
board will most likely break your build.

CMOS offset for VbNv data. This value must match cmos.layout
in the mainboard directory, minus 14 bytes for the RTC.

VBNV is stored in CMOS
config CHROMEOS_VBNV_CMOS_BACKUP_TO_FLASH

Vboot non-volatile storage data will be backed up from CMOS to flash
and restored from flash if the CMOS is invalid due to power loss.

default n
depends on VBOOT_VERIFY_FIRMWARE
help
EC software sync is a mechanism where the AP helps the EC verify its
firmware similar to how vboot verifies the main system firmware. This
option selects whether depthcharge should support EC software sync.
config VBOOT_EC_SLOW_UPDATE
bool "EC is slow to update"
default n
depends on EC_SOFTWARE_SYNC
help
Whether the EC (or PD) is slow to update and needs to display a
screen that informs the user the update is happening.
config VBOOT_OPROM_MATTERS
bool "Video option ROM matters (= can skip display init)"
default n
depends on VBOOT_VERIFY_FIRMWARE
help
Set this option to indicate to vboot that this platform will skip its
display initialization on a normal (non-recovery, non-developer) boot.
Vboot calls this "oprom matters" because on x86 devices this
traditionally meant that the video option ROM will not be loaded, but
it works functionally the same for other platforms that can skip their
native display initialization code instead.
config VIRTUAL_DEV_SWITCH
bool "Virtual developer switch support"
default n
depends on VBOOT_VERIFY_FIRMWARE
help
Whether this platform has a virtual developer switch.
config VBOOT_VERIFY_FIRMWARE
bool "Verify firmware with vboot."
default n
depends on HAVE_HARD_RESET
help
Enabling VBOOT_VERIFY_FIRMWARE will use vboot to verify the components
of the firmware (stages, payload, etc).
config NO_TPM_RESUME
bool
default n
help
On some boards the TPM stays powered up in S3. On those
boards, booting Windows will break if the TPM resume command
is sent during an S3 resume.
config PHYSICAL_REC_SWITCH

Whether this platform has a physical recovery switch
config LID_SWITCH

When this option is enabled, the firmware provides the ability to
signal the application the need for factory reset (a.k.a. wipe
out) of the device
