FS#9730 by Torne Wuff - support installing Rockbox in the firmware partition in place of the main Apple firmware. This image is only loaded if no rockbox.ipod is found so does not affect current behaviour. The advantage is a small increase in boottime. This patch also adds documentation to bootloader/ipod.c in the form of a comment describing the booting behaviour.
