Initial commit for the Olympus m:robe 100 port (PP5020). The LCD driver works. The ADC driver was copied from the H10 port (they can probably be combined later), but the battery readings aren't right and it shuts down. The touch pad buttons do not work. Install the bootloader and rockbox the H10 way. Still lots of work to do.
