[U-Boot] [PATCH for-next 0/3] sunxi: Kconfig consolidation and cleanup

[Ian Campbell <ijc@hellion.org.uk>]

A few simple patches which consolidate some Kconfig options and make
SPL_FEL a first class .config member instead of putting it in
CONFIG_SYS_EXTRA_OPTIONS.

This means it is possible to do a FEL build for any board with:
        make <board>_config
        echo CONFIG_SPL_FEL=y >> .config
        echo CONFIG_SPL_FEL=y >> spl/.config
or better
        make <board>_config
        sed -i -e 's/\# CONFIG_SPL_FEL is not set/CONFIG_SPL_FEL=y/g' .config spl/.config
which is still one more step than I would like but still preferable IMHO
to:
	sed -i -e 's/^CONFIG_SYS_EXTRA_OPTIONS="[^"]*/&,SPL_FEL/g' .config spl/.config

I've been using a little hack (below) to MAKEALL to help build test
this.

There's still plenty of stuff in sunxi CONFIG_SYS_EXTRA_OPTIONS which
could be moved out, but most of it is dependent on drivers/*/Kconfig
switching first.

Probably the board and power controller selection could be moved out
without any dependencies, although the board one in particular will be
quite a big patch I think it would be worth it.

Ian.

My MAKEALL hack, surely not upstreamable ;-)
