just add this function to bootloader.
when you press [M] + [POWER] the bootloader will 
pass [1] to kernel. boot to sd card

without the [M]. bootloader will boot to nand
by pass [2] to kernel.

[1]"mem=32M console=ttyS0,57600n8 rootfstype=ext2 root=/dev/mmcblk0p1 rw rootwait"
[2]"mem=32M console=ttyS0,57600n8 ubi.mtd=2 rootfstype=ubifs root=ubi0:rootfs rw rootwait"
