+	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"

+	  Enabling this option will pass "-Os" instead of "-O2" to gcc

+
+	  This option is enabled by default for U-Boot.
+
+config SYS_MALLOC_F
+	bool "Enable malloc() pool before relocation"
+	default y if DM
+	help
+	  Before relocation memory is very limited on many platforms. Still,
+	  we can provide a small malloc() pool if needed. Driver model in

+	  This option allows certain base U-Boot options and settings
+	  to be disabled or tweaked. This is for specialized

+	  Only use this if you really know what you are doing.
+
+if EXPERT
+	config SYS_MALLOC_CLEAR_ON_INIT
+	bool "Init with zeros the memory reserved for malloc (slow)"
+	default y
+	help
+	  This setting is enabled by default. The reserved malloc
+	  memory is initialized with zeros, so first malloc calls
+	  will return the pointer to the zeroed memory. But this
+	  slows the boot time.
+
+	  It is recommended to disable it, when CONFIG_SYS_MALLOC_LEN
+	  value, has more than few MiB, e.g. when uses bzip2 or bmp logo.
+	  Then the boot time can be significantly reduced.
+	  Warning:
+	  When disabling this, please check if malloc calls, maybe
+	  should be replaced by calloc - if expects zeroed memory.

+	  function, it is possible for the stack to move there before
