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.

100 depends on SPL
101 bool "Enable SDRAM location for SPL stack"
102 help
103 SPL starts off execution in SRAM and thus typically has only a small
104 stack available. Since SPL sets up DRAM while in its board_init_f()
105 function, it is possible for the stack to move there before
106 board_init_r() is reached. This option enables a special SDRAM
107 location for the SPL stack. U-Boot SPL switches to this after
108 board_init_f() completes, and before board_init_r() starts.

Masahiro Yamadaed363232014-09-16 16:32:58 +0900153 provided the extra options field. If you have something like
Masahiro Yamada51631252014-07-30 14:08:15 +0900154 "HAS_BAR,BAZ=64", the optional options
155 #define CONFIG_HAS
156 #define CONFIG_BAZ 64
157 will be defined in include/config.h.
158 This option was prepared for the smooth migration from the old
159 configuration to Kconfig. Since this option will be removed sometime,
160 new boards should not use this option.
