* Make the Gigabeat S bootloader a bit more interesting: it looks for the first firmware file it finds on the second partition and attempts to load it. Loading fails to get past the splash screen though.
* Make the main binary compile. To send a firmware file, use mtp-sendfile. To update you'll need to delete the previous firmware file, as files are named sequentially and the first one is loaded. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15836 a1c6a512-1295-4272-9138-f99709370657
