18	string "Local version - append to U-Boot release"
19	depends on !SPL_BUILD
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".)
48
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.

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

106	depends on !SPL_BUILD
107	help
108	  This option allows to boot the new uImage structrure,
109	  Flattened Image Tree.  FIT is formally a FDT, which can include
110	  images of various types (kernel, FDT blob, ramdisk, etc.)
111	  in a single blob.  To boot this new uImage structure,
112	  pass the the address of the blob to the "bootm" command.

126config SYS_EXTRA_OPTIONS
127	string "Extra Options (DEPRECATED)"
128	depends on !SPL_BUILD
129	help
130	  The old configuration infrastructure (= mkconfig + boards.cfg)
131	  provided the extra options field. If you have something like
132	  "HAS_BAR,BAZ=64", the optional options
133	    #define CONFIG_HAS
134	    #define CONFIG_BAZ	64
135	  will be defined in include/config.h.
136	  This option was prepared for the smooth migration from the old
137	  configuration to Kconfig. Since this option will be removed sometime,
138	  new boards should not use this option.
