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.

28config LOCALVERSION_AUTO
29	bool "Automatically append version information to the version string"
30	depends on !SPL_BUILD
31	default y
32	help
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.
41
42	  (The actual string used here is the first eight characters produced
43	  by running the command:
44
45	    $ git rev-parse --verify HEAD
46
47	  which is done within the script "scripts/setlocalversion".)

49config CC_OPTIMIZE_FOR_SIZE
50	bool "Optimize for size"
51	depends on !SPL_BUILD
52	default y
53	help
54	  Enabling this option will pass "-Os" instead of "-O2" to gcc
55	  resulting in a smaller U-Boot image.
56
57	  This option is enabled by default for U-Boot.

90	string "Extra Options (DEPRECATED)"
91	depends on !SPL_BUILD
92	help
93	  The old configuration infrastructure (= mkconfig + boards.cfg)
94	  provided the extra options field. If 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.
