+	  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

+	  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
+
