[PATCHv2 0/9]

Hi everyone,

This patchset brings in support for the Allwinner A20 SoC.

This SoC is pretty much the heir of the Allwinner A10. They both have a lot of
IP in common, the A20 is pin-compatible with the A10, the only major difference
being that the A20 has 2 Cortex-A7 instead of the single Cortex-A8 found in the

Just like the A31, the SMP support isn't there yet, nor do we have clock
support or any storage device.

We also have the same SMP bit issue that makes Linux run without the caches
enabled for the time being when CONFIG_SMP isn't set.

This serie comes on top of the serie "ARM: sunxi: Add support for the Allwinner
A31 SoC" I sent previously.


Changes from v1:
  - Removed the patch that wrapped the compatibles in the clock driver
