config UBOOTVERSION
string
option env="UBOOTVERSION"
config KCONFIG_OBJDIR
string
option env="KCONFIG_OBJDIR"
menu "General setup"
config LOCALVERSION
string "Local version - append to U-Boot release"
depends on !SPL_BUILD
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"
depends on !SPL_BUILD
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"
depends on !SPL_BUILD
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.
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.

prompt "Enable TPL" if !SPL_BUILD
default y if TPL_BUILD

help
If you want to build TPL as well as the normal image and SPL, say Y.
config FIT
bool "Support Flattened Image Tree"
depends on !SPL_BUILD
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 "Enabel signature verification of FIT uImages"
depends on FIT
help
This option enables signature verification of FIT uImages,
using a hash signed and verified using RSA.
See doc/uImage.FIT/signature.txt for more details.
config SYS_EXTRA_OPTIONS
string "Extra Options (DEPRECATED)"
depends on !SPL_BUILD
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.
config SYS_TEXT_BASE
depends on SPARC
