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

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

39 (The actual string used here is the first eight characters produced
40 by running the command:
41
42 $ git rev-parse --verify HEAD

76 help
77 This option allows certain base U-Boot options and settings
78 to be disabled or tweaked. This is for specialized
79 environments which can tolerate a "non-standard" U-Boot.
80 Only use this if you really know what you are doing.

134 The old configuration infrastructure (= mkconfig + boards.cfg)
Masahiro Yamadaed363232014-09-16 16:32:58 +0900135 provided the extra options field. If you have something like
Masahiro Yamada51631252014-07-30 14:08:15 +0900136 "HAS_BAR,BAZ=64", the optional options
137 #define CONFIG_HAS
138 #define CONFIG_BAZ 64
139 will be defined in include/config.h.
140 This option was prepared for the smooth migration from the old
141 configuration to Kconfig. Since this option will be removed sometime,
142 new boards should not use this option.
