MultiBoot_Firmware
Stop gap till I get a chance to work on the root folder stuff
Makes whatever volume marked by bootdata.boot_volume
the base or root volume, mounts all other volumes after
the specified boot volume.
Has the effect of swapping the SD card to the slot for internal
and Internal storage is mounted as the Sd-card.
Does not honor root redirect -- uses .rockbox folder in the root of boot volume
