  21           Append an extra string to the end of your U-Boot version.
  22           This will show up on your boot log, for example.
  23           The string you set here will be appended after the contents of
  24           any files with a filename matching localversion* in your
  25           object and source tree, in that order.  Your total string can
  26           be a maximum of 64 characters.

  33           This will try to automatically determine if the current tree is a
  34           release tree by looking for git tags that belong to the current
  35           top of tree revision.
  36
  37           A string of the format -gxxxxxxxx will be added to the localversion
  38           if a git-based tree is found.  The string generated by this will be
  39           appended after any matching localversion* files, and after the value
  40           set in CONFIG_LOCALVERSION.

  42           (The actual string used here is the first eight characters produced
  43           by running the command:
  44
  45             $ git rev-parse --verify HEAD

  54           Enabling this option will pass "-Os" instead of "-O2" to gcc
  55           resulting in a smaller U-Boot image.

 100           The old configuration infrastructure (= mkconfig + boards.cfg)
 101           provided the extra options field. If you have something like
 102           "HAS_BAR,BAZ=64", the optional options
 103             #define CONFIG_HAS
 104             #define CONFIG_BAZ  64
 105           will be defined in include/config.h.
 106           This option was prepared for the smooth migration from the old
 107           configuration to Kconfig. Since this option will be removed sometime,
 108           new boards should not use this option.
