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.
