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

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

Masahiro Yamadaed363232014-09-16 16:32:58 +0900[diff] [blame]131 provided the extra options field. If you have something like
Masahiro Yamada51631252014-07-30 14:08:15 +0900[diff] [blame]132 "HAS_BAR,BAZ=64", the optional options
133 #define CONFIG_HAS
134 #define CONFIG_BAZ 64
135 will be defined in include/config.h.
136 This option was prepared for the smooth migration from the old
137 configuration to Kconfig. Since this option will be removed sometime,
138 new boards should not use this option.
