Subject: Denali NAND driver on SocKit

Hi!

I'm trying to get NAND to work on socdk board... but it looks like
neccessary device tree bindings are not there. And when I do add them,
they don't seem to work.

Does it work for you? Is there patch I should apply?

Thanks,
Pavel

Ok, I know what went wrong. I got confused. It seems there is no nand
connected to denali on sockit board.

Best regards,
