config LOCALVERSION
	string "Local version - append to U-Boot release"
	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"
	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"
	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.

	default 0x400
	help
	  Before relocation memory is very limited on many platforms. Still,
	  we can provide a small malloc() pool if needed. Driver model in
	  particular needs this to operate, so that it can allocate the
	  initial serial device and any others that are needed.

        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.

config SPL_STACK_R
	depends on SPL
	bool "Enable SDRAM location for SPL stack"
	help
	  SPL starts off execution in SRAM and thus typically has only a small
	  stack available. Since SPL sets up DRAM while in its board_init_f()
	  function, it is possible for the stack to move there before
	  board_init_r() is reached. This option enables a special SDRAM
	  location for the SPL stack. U-Boot SPL switches to this after
	  board_init_f() completes, and before board_init_r() starts.

config SPL_STACK_R_ADDR
	depends on SPL_STACK_R
	hex "SDRAM location for SPL stack"
	help
	  Specify the address in SDRAM for the SPL stack. This will be set up
	  before board_init_r() is called.

	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.

	  using a hash signed and verified using RSA. If
	  CONFIG_SHA_PROG_HW_ACCEL is defined, i.e support for progressive

config SYS_EXTRA_OPTIONS
	string "Extra Options (DEPRECATED)"
	help
	  The old configuration infrastructure (= mkconfig + boards.cfg)
153
	  provided the extra options field. If you have something like
154 155 156 157 158 159 160 161
	  "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.
