	  The fastboot protocol requires a large memory buffer for
	  downloads. This buffer should be as large as possible for a
	  platform. Define this to the size available RAM for fastboot.

	help
	  The fastboot "flash" command supports writing the downloaded
	  image to the Protective MBR and the Primary GUID Partition
	  Table. (Additionally, this downloaded image is post-processed
	  to generate and write the Backup GUID Partition Table.)
	  This occurs when the specified "partition name" on the
	  "fastboot flash" command line matches the value defined here.
	  The default target name for updating GPT is "gpt".

config FASTBOOT_MBR_NAME
	string "Target name for updating MBR"
	depends on FASTBOOT_FLASH_MMC && DOS_PARTITION
	default "mbr"

	  The fastboot "flash" command allows to write the downloaded image
	  to the Master Boot Record. This occurs when the "partition name"
	  specified on the "fastboot flash" command line matches the value
	  defined here. The default target name for updating MBR is "mbr".

config FASTBOOT_CMD_OEM_FORMAT

	help
	  Add support for the "oem format" command from a client. This

	  partitions as required by the gpt command.
