[U-Boot] [PATCH] mx28evk: add NAND support

[Lauri Hintsala]

NAND support is not enabled by default because Eval Kit is not delivered
with NAND chip. To enable NAND support add CONFIG_CMD_NAND to board config.

I think we can schedule it for .04 release as this is basically a fix? Fabio ?

Looks good to me. My only suggestion (can be part of a separate patch)
is to modify the mx28evk README and explain that mx28evk can also boot
from NAND and explain the boot mode settings, etc.

Thanks,

Good idea, but let's do this in a separate patch :)

Well, this is not a fix because it adds a feature that is not yet
supported. It should be deferred to the next release.
