======================================== Do not apply this patch to the main line ========================================
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 - arch/${ARCH}/configs/*_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.
