+         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.

+         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
+

+          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.
