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.
59 endmenu # General setup
62 bool "Configure standard U-Boot features (expert users)"
64 This option allows certain base U-Boot options and settings
65 to be disabled or tweaked. This is for specialized
66 environments which can tolerate a "non-standard" U-Boot.
67 Only use this if you really know what you are doing.

90 prompt "Enable SPL" if !SPL_BUILD
91 default y if SPL_BUILD
93 If you want to build SPL as well as the normal image, say Y.

98 prompt "Enable TPL" if !SPL_BUILD
99 default y if TPL_BUILD
102 If you want to build TPL as well as the normal image and SPL, say Y.
104 config SYS_EXTRA_OPTIONS
105 string "Extra Options (DEPRECATED)"
106 depends on !SPL_BUILD
108 The old configuration infrastructure (= mkconfig + boards.cfg)
109 provided the extra options field. If you have something like
110 "HAS_BAR,BAZ=64", the optional options
112 #define CONFIG_BAZ 64
113 will be defined in include/config.h.
114 This option was prepared for the smooth migration from the old
115 configuration to Kconfig. Since this option will be removed sometime,
116 new boards should not use this option.
