	  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.

	help
	  EC software sync is a mechanism where the AP helps the EC verify its

	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

	  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
