config EXPERT
	bool "Expert mode"
	help
	  This allows you to select certain advanced configuration options.

	  Warning: Only enable this option if you really know what you are
	  doing! You have been warned!

config LOCALVERSION
	string "Local version string"
	help
	  Append an extra string to the end of the coreboot version.

	  This can be useful if, for instance, you want to append the
	  respective board's hostname or some other identifying string to
	  the coreboot version number, so that you can easily distinguish
	  boot logs of different boards from each other.

	  This Option is unused in the code.  Since two boards try to set it to

config PAYLOAD_NONE
	bool "None"
	help
	  Select this option if you want to create an "empty" coreboot
	  ROM image for a certain mainboard, i.e. a coreboot ROM image
	  which does not yet contain a payload.

	  For such an image to be useful, you have to use 'cbfstool'
	  to add a payload to the ROM image later.

config PAYLOAD_ELF
	bool "An ELF executable payload"
	help
	  Select this option if you have a payload image (an ELF file)
	  which coreboot should run as soon as the basic hardware
	  initialization is completed.

	  You will be able to specify the location and file name of the
	  payload image later.

endchoice

config FALLBACK_PAYLOAD_FILE

	  image later.

config FALLBACK_VGA_BIOS_FILE
	string "VGA BIOS path and filename"

	  The path and filename of the file to use as VGA BIOS.

config FALLBACK_VGA_BIOS_ID
	string "VGA device PCI IDs"

	help
	  The comma-separated PCI vendor and device ID that would associate
	  your VGA BIOS to your video card.

	  Example: 1106,3230

	  In the above example 1106 is the PCI vendor ID (in hex, but without
	  the "0x" prefix) and 3230 specifies the PCI device ID of the
	  video card (also in hex, without "0x" prefix).
