Can we get rid of the extra options for NAND? I think it can be replaced 
by CONFIG_NAND_BOOT, can't it?

I have sent a patch to get rid of the LS2080A do you don't have to worry 
about that. http://patchwork.ozlabs.org/patch/746782/

This is exactly what I was thinking. So we don't need the CONFIG_NAND 
macro. After this patch, can you sent another clean up patch to remove 
other CONFIG_NAND macros? You don't have to respin this patch.
