Hello.

The current size of the kernel partition is sufficient to place i.MX51-dependent code only,
but if the kernel was compiled with support for other boards / drivers, the space is too small.
Installing the kernel in rootfs might be a good idea, but that means that rootfs is a UBIFS,
and resulting ubifs image will be NAND type dependent. In order to use the same rootfs on
different systems, I prefer to use the squashfs root filesystem on top of the UBI volume.

Let's just drop this patch.
