It makes sense to specify CONFIG_SYS_CLK_FREQ in "configs/xx_defconfig" instead of "include/configs/xxx.h" because then header will be reusable across boards with different CPU clocks. Also this nice to have an ability for end user to tune this value himself via "menuconfig". For now I'm only applying this change to all ARC configs because otherwise scope of change will be huge.

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".)

This option allows certain base U-Boot options and settings

images of various types (kernel, FDT blob, ramdisk, etc.)

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

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.
