This patch adds the maps for the taco. It also gets the ndfc.c NAND 
driver in a compilable state. The map is guaranteed to change since the 
exact NOR/NAND flash configuration is in flux right now when we found 
the 256M NAND flash won't boot properly.

Currently it configures the NOR in a reasonable fashion and leaves the 
NAND as one honkin' parition.
