9 option env="UBOOTVERSION"
13 option env="KCONFIG_OBJDIR"
18 string "Local version - append to U-Boot release"
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.
28 config LOCALVERSION_AUTO
29 bool "Automatically append version information to the version string"
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
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:
45 $ git rev-parse --verify HEAD
47 which is done within the script "scripts/setlocalversion".)
49 config CC_OPTIMIZE_FOR_SIZE
50 bool "Optimize for size"
54 Enabling this option will pass "-Os" instead of "-O2" to gcc
55 resulting in a smaller U-Boot image.
57 This option is enabled by default for U-Boot.

94 If you want to build TPL as well as the normal image and SPL, say Y.
96 config SYS_EXTRA_OPTIONS
97 string "Extra Options (DEPRECATED)"
100 The old configuration infrastructure (= mkconfig + boards.cfg)
101 provided the extra options field. If you have something like
102 "HAS_BAR,BAZ=64", the optional options
104 #define CONFIG_BAZ 64
105 will be defined in include/config.h.
106 This option was prepared for the smooth migration from the old
107 configuration to Kconfig. Since this option will be removed sometime,
108 new boards should not use this option.
