Hi everyone,

This patch series adds very basic support for Allwinner's A80 SoC,
a big.LITTLE architecture with 4 Cortex-A7s and 4 Cortex-A15s.

Development is done on the A80 Optimus Board, the defacto development
board for the A80, with the accompanying SDK as a reference. 

So far I've been unable to get the board to boot from MMC, or
using Android fastboot. I'm using Allwinner's FEL mode to load
the bootloader and kernel+dtb image over USB. Notes on my attempts
can be found here: http://linux-sunxi.org/User:Wens#A80_Optimus

Patch 1 introduces the compatible string for the A80.

Patch 2 adds options to use UART0 on the A80 as the debug port for
earlyprintk.

Patch 3 adds a barebone dtsi with just the cpu, memory and uart nodes.

Patch 4 adds a barebone dts for the A80 Optimus Board.

Patch 5 documents the vendor prefix for Merrii Technology Co., Ltd,
the designer and vendor of the A80 Optimus Board.

Patch 6 documents all the Allwinner SoCs we currently support.

Cheers
ChenYu
