What is this tool?
------------------
This tool converts boards.cfg to defconfig and Kconfig files.
It automatically generates
- arch/${ARCH}/Kconfig
- board/${VENDOR}/${BOARD}/Kconfig
- board/${BOARD}/Kconfig
- configs/${TARGET_BOARD}_defconfig
How to use?
-----------
Open tools/print_allconfigs with an editor.
Adjust cross compilers part for your environment.
# Specify your favoriate cross tools
CROSS_COMPILE_ARC=arc-linux-
CROSS_COMPILE_AARCH64=aarch64-linux-gnu-
CROSS_COMPILE_ARM=arm-unknown-linux-gnueabi-
[snip]
CROSS_COMPILE_X86=i386-linux-
And then, run "tools/genkconfig".
Why is this patch here?
-----------------------
The file boards.cfg is touched very frequently.
All the time, new/old boards are being added/removed.
The next commit was generated based on the u-boot/master at the time
I posted it.
It will become out-dated soon.
You can update it with this tool.

Changes in v5:
- Add CPU select menu for PowerPC
Changes in v4:
- Remove debug code
- Do not specify CONFIG_SYS_CPU if the cpu field of boards.cfg is '-'
- Adjust to the current boards.cfg fields spec.
- Add "select CPU" to PowerPC Kconfig
- Generate only one defconfig per board
Changes in v3:
- Create SPL defconfig into configs/<board>_spl_defconfig
instead of conigs/spl/<board>_defconfig. Like the same for TPL.
Because I want to handle Falcon boot more genericlly.
If you build only configs/<board>_spl_defconfig, it is Falcon boot.
- Create board select menu based on the 8th field of boards.cfg.
It is common that many entries (= 7th field) share the same
config header. So this change help to reduce the code redandancy.
Changes in v2:
- Do not output CONFIG_BOARD_MAINTAINERS and CONFIG_BOARD_STATUS
- Delete board/Kconfig and move "source board/*/*/Kconfig"
statements to arch/*/Kconfig.
