I use an initramfs to mount root indeed. This is just an alternative to
7 patches in generic and mvebu to do the same.

The kernel partition is 6MB, so there is plenty space and using busybox
works fine except there is no ubiblock applet. To work around this I
build ubi as a module instead of built-in and use module parameter to
create a blockdevice from the squashfs volume for use by the overlayfs.

Cheers
Ralph
