Camd_nemo

This is a camd.library driver for the second on-board UART built-in to the 
PA6T processor used on the AmigaOne X1000. It supports both MIDI in and MIDI
out, and uses an interrupt driver for input.

The driver hits the hardware directly, and only needs camd.library v53 to work.

To install, copy the file NEMO to devs/MIDI.

You will need some hardware to convert the ports RS232 levels to MIDIs 5v 
current loop, the circuit I used can be found here:

I have replace the 9 pin connector with a 3 pin header, which connects to 
the port (marked RS232 #1) on the motherboard. Finding 5V power for the
circuit shouldn't be to hard!

Full source is included, and this could probably be converted for other 
systems that have PC16550 serial ports on if needed.

This is based on the EnvyHT24 camd driver by Davy Wentzler
