Hi everyone,

This patchset add support in Linux for the Allwinner A31 SoC. This SoC is
the
current high-end Allwinner SoC, and is powered by 4 Cortex-A7.

SMP support is not there yet, but should come eventually, so does the clock
support.

As usual, since we don't have any storage device driver yet, it only boots
from
an initramfs.

Finally, something worth mentionning is that with the current bootloader,
you'll encounter 2 ~6s hangs during the boot. This is because the SMP bit
of
the Cortex-A7 doesn't appear to be set, leading to the CPU caches being
disabled. This can partially be addressed by selecting CONFIG_SMP, that
will
remove the second hang, because the SMP bit is set after kernel
decompression.

Obviously, this won't remove the first hang that happens during
decompression,
but it's better than nothing. A proper fix would be to fix the bootloader.

Thanks,
Maxime
