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

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

45 (The actual string used here is the first eight characters produced
46 by running the command:
47
48 $ git rev-parse --verify HEAD

84 This option allows certain base U-Boot options and settings
85 to be disabled or tweaked. This is for specialized
86 environments which can tolerate a "non-standard" U-Boot.
87 Only use this if you really know what you are doing.

154 The old configuration infrastructure (= mkconfig + boards.cfg)
Masahiro Yamadaed363232014-09-16 16:32:58 +0900155 provided the extra options field. If you have something like
Masahiro Yamada51631252014-07-30 14:08:15 +0900156 "HAS_BAR,BAZ=64", the optional options
157 #define CONFIG_HAS
158 #define CONFIG_BAZ 64
159 will be defined in include/config.h.
160 This option was prepared for the smooth migration from the old
161 configuration to Kconfig. Since this option will be removed sometime,
162 new boards should not use this option.
