Thanks, works like a charm.

I've applied the entire series to my tree, except for
"[PATCH 3/6] arm: Allow u32 as addrs for readX/writeX"
instead I've added 2 extra casts to your
"[PATCH 4/6] sunxi: Explicitly cast u32 pointer conversions"
patch, which is enough to build warning free for me.

I still have some other patches to process, I'll send a pull-req
tomorrow morning.

Note I've squashed the following fixes into
"[PATCH 5/6] sunxi: Add support for Allwinner A64 SoCs" :
