Similar to the rootfs hacks on NOR flash devices, this series
introduces support for auto-attaching (ubi device), auto-creating
(ubiblock device) and mounting the "rootfs" (ubifs or squashfs)
volume.
This is needed so OpenWrt can start without relying on the bootloader
to pass the ubi.mtd, ubi.block, rootfs and rootfstype parameters, but
instead auto-detect the root filesystem according to a simple convention.
OpenWrt-specific:
