    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.
    
    
    config SYS_MALLOC_F
    	bool "Enable malloc() pool before relocation"
    	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.

    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.

    config FIT
    	bool "Support Flattened Image Tree"
    	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

    	depends on DM
    
    	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)"
    	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.
