Ack, the "FIXUP" marked patched in my series are intented to get squashed
into your patches.

You mean merging u-boot-sunxi's sunxi branch to v2014.04-rc2 right? That sounds
fine to me. Ultimately its HNO call to make though. HNO if you're ok with this
I can test Ian's merge on sun4i and sun5i and then push it to u-boot-sunxi's sunxi
branch.

Yes a git pull is probably best. You can use either github's pull-req
interface or just send one to the linux-sunxi list.

Sounds good.

Ok, so lets split up our efforts for now then, you work on getting the basic
sun7i support upstream and I'll work on adding missing bits, like sun4i, sun5i
and axp support.

p.s.

For those reading along, I've just finished adding sun5i support, testing that
is next on my todo list, then adding axp support. I'll send a second patch-set
with what I've tonight to avoid others doing double work. In general my latest
work on this can be found here:
