[Oberon] Oberon bare metal on the Raspberry Pi

[Charles Perkins]

Not yet -- I took some significant liberties with the source code to the ORP compiler in the RISC image and I would need permission from the original authors to make the modified source available.  I am very grateful for their willingness to put on-line what they have done so far, I don't want to dissuade them from further sharing!

The compiler I am using right now is not the compiler you want anyway. It is very much a work-in-progress (e.g. a hack.)

Better compilers will come!
