11 # Allow defaults in arch-specific code to override any given here
17 string "Local version - append to U-Boot release"
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.
26 config LOCALVERSION_AUTO
27 bool "Automatically append version information to the version string"
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
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:
42 $ git rev-parse --verify HEAD
44 which is done within the script "scripts/setlocalversion".)
46 config CC_OPTIMIZE_FOR_SIZE
47 bool "Optimize for size"
50 Enabling this option will pass "-Os" instead of "-O2" to gcc
51 resulting in a smaller U-Boot image.
53 This option is enabled by default for U-Boot.
56 bool "Enable malloc() pool before relocation"
59 Before relocation memory is very limited on many platforms. Still,
60 we can provide a small malloc() pool if needed. Driver model in
61 particular needs this to operate, so that it can allocate the
62 initial serial device and any others that are needed.
64 config SYS_MALLOC_F_LEN
65 hex "Size of malloc() pool before relocation"
66 depends on SYS_MALLOC_F
69 Before relocation memory is very limited on many platforms. Still,
70 we can provide a small malloc() pool if needed. Driver model in
71 particular needs this to operate, so that it can allocate the
72 initial serial device and any others that are needed.
75 bool "Configure standard U-Boot features (expert users)"
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.

94 depends on SUPPORT_SPL
97 If you want to build SPL as well as the normal image, say Y.
101 depends on SPL && SUPPORT_TPL
104 If you want to build TPL as well as the normal image and SPL, say Y.
107 bool "Support Flattened Image Tree"
109 This option allows to boot the new uImage structrure,
110 Flattened Image Tree. FIT is formally a FDT, which can include
111 images of various types (kernel, FDT blob, ramdisk, etc.)
112 in a single blob. To boot this new uImage structure,
113 pass the the address of the blob to the "bootm" command.
116 bool "Display verbose messages on FIT boot"
120 bool "Enable signature verification of FIT uImages"
125 This option enables signature verification of FIT uImages,
126 using a hash signed and verified using RSA. If
127 CONFIG_SHA_PROG_HW_ACCEL is defined, i.e support for progressive
128 hashing is available using hardware, RSA library will use it.
129 See doc/uImage.FIT/signature.txt for more details.
131 config SYS_EXTRA_OPTIONS
132 string "Extra Options (DEPRECATED)"
134 The old configuration infrastructure (= mkconfig + boards.cfg)
135 provided the extra options field. If you have something like
136 "HAS_BAR,BAZ=64", the optional options
138 #define CONFIG_BAZ 64
139 will be defined in include/config.h.
140 This option was prepared for the smooth migration from the old
141 configuration to Kconfig. Since this option will be removed sometime,
142 new boards should not use this option.
