Currently, I am updating this page:

http://rhombus-tech.net/allwinner_a10/Building_Linux/

On which I noted that the boot page...

http://rhombus-tech.net/allwinner/a20/boot/

...provides a special configuration (eoma68-a20-4.7-config) that would 
presumably get copied into the configs directory as some kind of defconfig. 
However, it is probably superseded by the sunxi_defconfig file now, for the 
most part.

It looks like the device tree (sun7i-a20-eoma68-a20.dts) is very similar to 
that from the Cubietruck 2. Were the differences documented and are there any 
schematics to provide any necessary insight when updating the device tree? 
(Since these things appear to change all the time - or just decay - in the 
Linux kernel distribution.)
