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".)

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

93 The old configuration infrastructure (= mkconfig + boards.cfg)
94 provided the extra options field. It you have something like
95 "HAS_BAR,BAZ=64", the optional options
96 #define CONFIG_HAS
97 #define CONFIG_BAZ 64
98 will be defined in include/config.h.
99 This option was prepared for the smooth migration from the old
100 configuration to Kconfig. Since this option will be removed sometime,
101 new boards should not use this option.
