Chen,

Many thanks for working on this!

Just a quick not for people celebrating too early, this is the *incomplete*
sun7i support from the linux-sunxi/u-boot-sunxi git repo. It is fine to
merge this upstream, but this does not include SPL support.

This allows replacing u-boot.bin on allwinnner sd-card images, which is
very useful. But it does not get us all the way to booting sun7i devices
we still need boot0 and boot1 binaries from allwinner for that (for now).

Regards,

Hans
