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.

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".)

Enabling this option will pass "-Os" instead of "-O2" to gcc

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.

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.)

pass the the address of the blob to the "bootm" command.

CONFIG_SHA_PROG_HW_ACCEL is defined, i.e support for progressive

hashing is available using hardware, RSA library will use it.

config SYS_EXTRA_OPTIONS

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.
