Hi,
You'll find in this patchset the initial support for Allwinner A10 and A13 SoCs
from Allwinner. Since the internal name of these SoCs are sun4i and sun5i, the
mach- directory is named sunxi.
You can find these SoCs in the Cubieboard, the A13-olinuxino or the Melee
A1000.
Both SoCs should work fine, as the A13 is a trimmed down version of the A10,
but it has only been tested on a A13-OlinuXino from Olimex.
Support is quite minimal for now, since it only includes timer and IRQ
controller drivers, so we can only boot to userspace through initramfs. Support
for the other peripherals on these SoCs will come eventually.
Thanks,
Maxime
