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 Change-Id: I0f786aa0c8721e21cba607366775be3e3c0cf474
