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 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.
