/*
The bootloader does nothing and it's not needed (it was used to test different
stuff only), because the original bootloader stored in the flash has ability to 
boot three different images in the SYSTEM directory:
jukebox.mi4 - when Power is pressed,
blupd.mi4 - when Power+C combo is used,
tester.mi4 - when Power+OK combo is used.

So we can use it to dual boot (for example renaming original jukebox.mi4 to 
tester.mi4 and the rockbox.mi4 to jukebox.mi4).
