OMAP3 pandora.
What I wanted to say is that current mainline code has hw ECC forced
which is wrong for some boards, and this patch did not make into last
merge window, so NAND is broken. It would be good to take this patch
out of larger series you sent earlier and resend as a fix for -rc1, so
that NAND works on 2.6.37.  It's not too large and should probably be
ok for -rc2.
