config LOCALVERSION
string "Local version - append to U-Boot release"
help
Append an extra string to the end of your U-Boot version.
This will show up on your boot log, for example.
The string you set here will be appended after the contents of
any files with a filename matching localversion* in your
object and source tree, in that order. Your total string can
be a maximum of 64 characters.
config LOCALVERSION_AUTO
bool "Automatically append version information to the version string"
default y
help
This will try to automatically determine if the current tree is a
release tree by looking for git tags that belong to the current
top of tree revision.
A string of the format -gxxxxxxxx will be added to the localversion
if a git-based tree is found. The string generated by this will be
appended after any matching localversion* files, and after the value
set in CONFIG_LOCALVERSION.
(The actual string used here is the first eight characters produced
by running the command:
$ git rev-parse --verify HEAD
which is done within the script "scripts/setlocalversion".)
config CC_OPTIMIZE_FOR_SIZE
bool "Optimize for size"
default y
help
Enabling this option will pass "-Os" instead of "-O2" to gcc
resulting in a smaller U-Boot image.
This option is enabled by default for U-Boot.
config SYS_MALLOC_F
bool "Enable malloc() pool before relocation"
default 0x400
help
Before relocation memory is very limited on many platforms. Still,
we can provide a small malloc() pool if needed. Driver model in
particular needs this to operate, so that it can allocate the
initial serial device and any others that are needed.
config SYS_MALLOC_F_LEN
hex "Size of malloc() pool before relocation"
depends on SYS_MALLOC_F
default 0x400
help

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

config FIT
bool "Support Flattened Image Tree"
help
This option allows to boot the new uImage structrure,
Flattened Image Tree. FIT is formally a FDT, which can include
images of various types (kernel, FDT blob, ramdisk, etc.)
in a single blob. To boot this new uImage structure,
pass the the address of the blob to the "bootm" command.
config FIT_VERBOSE
bool "Display verbose messages on FIT boot"
depends on FIT
config FIT_SIGNATURE
bool "Enable signature verification of FIT uImages"
depends on FIT
depends on DM
select RSA
help
This option enables signature verification of FIT uImages,
using a hash signed and verified using RSA. If
CONFIG_SHA_PROG_HW_ACCEL is defined, i.e support for progressive
hashing is available using hardware, RSA library will use it.
See doc/uImage.FIT/signature.txt for more details.
config SYS_EXTRA_OPTIONS
string "Extra Options (DEPRECATED)"
help
The old configuration infrastructure (= mkconfig + boards.cfg)
provided the extra options field. If you have something like
"HAS_BAR,BAZ=64", the optional options
#define CONFIG_HAS
#define CONFIG_BAZ 64
will be defined in include/config.h.
This option was prepared for the smooth migration from the old
configuration to Kconfig. Since this option will be removed sometime,
new boards should not use this option.
