If we must start using NAND rather than CMD_NAND to enable the NAND subsystem (which is what this patch does), then a lot more than that needs to change. We'll need a new name for the boot source selection, and we'll need to kconfigize all the boards that enable CONFIG_CMD_NAND via the board config header. -Scott
