	  The firmware image has to store more than just coreboot, including:

	  This option allows to limit the size of the CBFS portion in the

config PRE_GRAPHICS_DELAY

	help
	  On some systems, coreboot boots so fast that connected monitors
	  (mostly TVs) won't be able to wake up fast enough to talk to the

	  the VBIOS.

config RESET_ON_INVALID_RAMSTAGE_CACHE

	help
	  The romstage code caches the loaded ramstage program in SMM space.
	  On S3 wake the romstage will copy over a fresh ramstage that was
	  cached in the SMM space. This option determines the action to take
	  when the ramstage cache is invalid. If selected the system will
	  reset otherwise the ramstage will be reloaded from cbfs.

config ME_MBP_CLEAR_LATE
	bool "Defer wait for ME MBP Cleared"
	default y
	help
	  If you set this option to y, the Management Engine driver
	  will defer waiting for the MBP Cleared indicator until the
	  finalize step.  This can speed up boot time if the ME takes
	  a long time to indicate this status.

config LOCK_MANAGEMENT_ENGINE
	bool "Lock Management Engine section"
	default n
	help
	  The Intel Management Engine supports preventing write accesses
	  from the host to the Management Engine section in the firmware
	  descriptor. If the ME section is locked, it can only be overwritten
	  with an external SPI flash programmer. You will want this if you
	  want to increase security of your ROM image once you are sure
	  that the ME firmware is no longer going to change.

	  If unsure, say N.
