Hi,

I just realised that I forgot to CC: the linux-sunxi list on this.
Could anyone please have a brief look and confirm that I didn't miss
anything in this update? It's mostly about adding DTs for new boards, so
that we can add U-Boot support for them. I would feel better merging my
own patches if someone confirms them ;-)

Cheers,
Andre.

P.S. There are discussions underway to automatically sync the DT rebase
repo into U-Boot, so we should get fresh DTs automatically:
