Allwinner A10 register guide

This page aims at documenting the known Allwinner A10 I/O registers. Any addresses in this document is using physical addressing.

How to contribute

Copy register information from headers in the kernel & u-boot sources, and hunt down what it means by reading how the registers are used in the sources.
