Notes

=====

Based on papyrus bsp which only really supports

the PowerOpen ABI with an ELF assembler.

For the multiprocessing tests to run, you must have a modified version of

the PowerPC Simulator psim which supports an area of UNIX shared memory

and UNIX semaphore mapped into the PowerPC address space.
