========================================
Do not apply this patch to the main line
========================================
What is this tool?
------------------
defconfig files for all target boards will be added in the next commit.
We already have more than 1000 boards.
Writing all defconfig files by hand is not realistic.
Instead, I wrote this ugly scripts to convert boards.cfg into defconfig.
How to use?
-----------
Check out this commit as HEAD.
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/gendefconfigs".
$ tools/gendefconfigs
generating configs/vexpress_aemv8a_defconfig
generating configs/axs101_defconfig
generating configs/arcangel4_defconfig
generating configs/arcangel4-be_defconfig
generating configs/integratorcp_cm1136_defconfig
generating configs/imx31_phycore_defconfig
generating configs/qong_defconfig
generating configs/mx31pdk_defconfig
...
Every defconfig files under configs/, spl/configs/, tpl/configs/
will be created/updated depending on boards.cfg.
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 defconfig files by yourself with this tool.
And We must re-generate defconfig files from the latest boards.cfg
just before applying this series.
I expect Tom will run this tool to make sure up-to-date defconfigs
to be merged.
