Just a note on the (lack of) documentation issue.

If there's a brave soul reading this and longing to tackle this,
the pxa3xx SoC documentation *is* publicly available:

http://www.marvell.com/application-processors/pxa-family/assets/PXA3xx_Developers_Manual.zip

The NAND specifications can be found in the "[...] Vol. II: Memory Controller" document,
inside the above zip file. IMHO, that's the reading entry point in order to
understand pxa3xx-nand driver better.
