config LOCALVERSION
	string "Local version - append to U-Boot release"
	depends on !SPL_BUILD
	help
	  Append an extra string to the end of your U-Boot version.
	  This will show up on your boot log, for example.
	  The string you set here will be appended after the contents of
	  any files with a filename matching localversion* in your
	  object and source tree, in that order.  Your total string can
	  be a maximum of 64 characters.

config LOCALVERSION_AUTO
	bool "Automatically append version information to the version string"
	depends on !SPL_BUILD
	default y
	help
	  This will try to automatically determine if the current tree is a
	  release tree by looking for git tags that belong to the current
	  top of tree revision.

	  A string of the format -gxxxxxxxx will be added to the localversion
	  if a git-based tree is found.  The string generated by this will be
	  appended after any matching localversion* files, and after the value
	  set in CONFIG_LOCALVERSION.

	  (The actual string used here is the first eight characters produced
	  by running the command:

	    $ git rev-parse --verify HEAD

	  which is done within the script "scripts/setlocalversion".)

config CC_OPTIMIZE_FOR_SIZE
	bool "Optimize for size"
	depends on !SPL_BUILD
	default y
	help
	  Enabling this option will pass "-Os" instead of "-O2" to gcc
	  resulting in a smaller U-Boot image.

	  This option is enabled by default for U-Boot.

menuconfig EXPERT
        bool "Configure standard U-Boot features (expert users)"
        help
          This option allows certain base U-Boot options and settings
          to be disabled or tweaked. This is for specialized
          environments which can tolerate a "non-standard" U-Boot.
          Only use this if you really know what you are doing.

	  If you want to build TPL as well as the normal image and SPL, say Y.

config FIT
	bool "Support Flattened Image Tree"
	depends on !SPL_BUILD
	help
	  This option allows to boot the new uImage structrure,
	  Flattened Image Tree.  FIT is formally a FDT, which can include
	  images of various types (kernel, FDT blob, ramdisk, etc.)
	  in a single blob.  To boot this new uImage structure,
	  pass the the address of the blob to the "bootm" command.

config FIT_VERBOSE
	bool "Display verbose messages on FIT boot"
	depends on FIT

config FIT_SIGNATURE
	bool "Enable signature verification of FIT uImages"
	depends on FIT
	select RSA
	help
	  This option enables signature verification of FIT uImages,
	  using a hash signed and verified using RSA.
	  See doc/uImage.FIT/signature.txt for more details.

config SYS_EXTRA_OPTIONS
	string "Extra Options (DEPRECATED)"
	depends on !SPL_BUILD
	help
	  The old configuration infrastructure (= mkconfig + boards.cfg)
	  provided the extra options field. If you have something like
	  "HAS_BAR,BAZ=64", the optional options
	    #define CONFIG_HAS
	    #define CONFIG_BAZ	64
	  will be defined in include/config.h.
	  This option was prepared for the smooth migration from the old
	  configuration to Kconfig. Since this option will be removed sometime,
	  new boards should not use this option.

config SYS_TEXT_BASE
	depends on SPARC
	hex "Text Base"
	help
	  TODO: Move CONFIG_SYS_TEXT_BASE for all the architecture

config SYS_CLK_FREQ
	depends on ARC
