Ok, I've managed to get things to work actually cold booting from the
sdcard slot (so as to not rely on earlier setup done by boot0 before
it enters FEL mode when pressin '2'). In order to get the sdcard +
cold booting to work I had to make some changes to the clk code:

With these fixes A83 support seems to work well, good job!

I've merged this into my sunxi-wip tree now and I'm preparing a pull-req
to send this upstream.

Regards,

Hans


p.s.

Next time please make sure to base your patches on the latest official
master, when you posted these patches master already had H3 support,
and I had to do quite a but of manual conflict resolving because of that.
