20 help
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

47 which is done within the script "scripts/setlocalversion".)

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

151 The old configuration infrastructure (= mkconfig + boards.cfg)
Masahiro Yamadaed363232014-09-16 16:32:58 +0900152 provided the extra options field. If you have something like
Masahiro Yamada51631252014-07-30 14:08:15 +0900153 "HAS_BAR,BAZ=64", the optional options
154 #define CONFIG_HAS
155 #define CONFIG_BAZ 64
156 will be defined in include/config.h.
157 This option was prepared for the smooth migration from the old
158 configuration to Kconfig. Since this option will be removed sometime,
159 new boards should not use this option.
