[U-Boot-Users] NAND driver updates

[Matthias Fuchs <matthias.fuchs@esd-electronics.com>]

Hi Stefan,

I totally agree with your suggestion. Let's move the NAND update into 
a separate branch for testing.

The missing or faulty NAND features are an absolute no-go because we
use NAND on many of our boards. But we definitely should not lose track
of the NAND updates. Especially William's YAFFS support is a cool outstanding
feature I would love to see in the main repo sooner or later.
