[Oberon] Raspberry Pi Revisited

Hi Jan,

I think you got confused with all these Peters here ;-) Jan was talking 
about Peter de Wachter. And there is also Peter Easthope here. 
Unfortunately Peter Muller left.

I am not in the details, but I am sure, GPIO can be accessed both, via 
memory mapped devices and read/write operations, also within Oberon 
Linux Revival on RPi.

If doing some hybrid (ARM/FPGA) staff I would recommend using existing 
hardware like MiST board. ( http://harbaum.org/till/mist/index.shtml )

Regards,
	Peter M.
