Looks like I'm going to have a requirement for one, so if no one has ....
well, its started.
Got a question, or two before getting started, though:
1. The "Porting" guide doesn't reflect the structure of the RTEMS directory,

2. How do the libbsp/libcpu directories get built into the "build" directory?

directory somehow? ... and if so.... how?
4. What "*.ac" files need to be modified to add the new architecture into the
5. Is newlib support a requirement? I now have a C compiler that efficently
compiles code for the processor, but there isn't any runtime support, to
