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

Hi! > CC: Graham Moore > > Graham should know more about this. Ok, I know what went wrong. I got confused. It seems there is no nand connected to denali on sockit board.
