These patches are designed to apply on top of sunxi-next. They depend on
Maxime Ripard's SPI patches for Allwinner A10 (sun4i).
I've watched the bus with a logic analyzer to make sure thing are sane, but
I'm only able to go up to 10MHz on my LA. Unfortunately, the SPI chip I was
using as a test device decided to die mid-way, so I was unable to test how
well full-duplex communication works on these large transfers
