	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 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

	  Enabling VBOOT_VERIFY_FIRMWARE will use vboot to verify the components
	  of the firmware (stages, payload, etc).

config NO_TPM_RESUME

	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.
