I think this thread initially reported two distinct defects, one has
been solved, the second one is in my hands but I couldn't find the root
cause yet. I tried to reproduce, without luck, with another NAND
controller. If someone has an imx based board and a NAND controller on
it, I would appreciate some help.

Thanks,
Miquèl
