	  Append an extra string to the end of your U-Boot version.
	  This will show up in 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

	  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.

	  It is recommended to disable it, when CONFIG_SYS_MALLOC_LEN
