Have you seen this ?
http://linux-sunxi.org/Mainline_Kernel_Howto

That works for me together with this kernel tree:
https://github.com/mripard/linux/tree/sunxi-next

But only if I use an appended ramdisk as advised, I've not
yet managed to get things to work with a separate ramdisk ...

Unfortunately I've not managed to get any further then that.

Last week I've just finished my last large project (usb-3 bulk
streams + uas support in both the kernel and qemu), so hopefully
soon I'll have time to really start looking into mmc support for
the upstream kernel. But first I'm going to take it easy a few
weeks (catching my breath after the big push I did at the end
of that last project).

Regards,

Hans
