	  The size of the cache-as-ram region required during bootblock
	  and/or romstage. Note DCACHE_RAM_SIZE and DCACHE_RAM_MRC_VAR_SIZE
	  must add up to a power of 2.

config DCACHE_RAM_MRC_VAR_SIZE

	  The amount of cache-as-ram region required by the reference code.

	  The amount of anticipated stack usage from the data cache
	  during pre-ram rom stage execution.

config HAVE_MRC

	help
	  Select this option to add a System Agent binary to
	  the resulting coreboot image.

	  Note: Without this binary coreboot will not work

config MRC_FILE

	  The path and filename of the file to use as System Agent
	  binary.

	help
	  On Haswell systems the firmware image has to store a lot more
	  than just coreboot, including:
	   - a firmware descriptor
	   - Intel Management Engine firmware
	   - MRC cache information
	  This option allows to limit the size of the CBFS portion in the
	  firmware image.

config PRE_GRAPHICS_DELAY
	int "Graphics initialization delay in ms"
	default 0
	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
	  VBIOS. On those systems we need to wait for a bit before executing
	  the VBIOS.
