========================================
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/${ARCH}/Kconfig
- board/Kconfig
- board/${VENDOR}/${BOARD}/Kconfig
- board/${BOARD}/Kconfig
- 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.
