I think we should remove "mem=128M" as we use device tree.
"mtdparts=atmel_nand:" \"8M(bootstrap/uboot/kernel)ro,-(rootfs) " \"root=/dev/mmcblk0p2 " \"rw rootfstype=ext4 rootwait"
Can we remove rootfstype, so it can compatible with ext2, ext3 and ext4.

Can we switch to zImage? As we try to support multi-platform with single image in kernel.
