When I wrote the ss555 port, I abstracted as much code as I could to the
mpc5xx library (in c/src/lib/libcpu/powerpc/mpc5xx), with the intention that
it be shared with future MPC5xx BSP's. Most of the remaining code in the
ss555 directory (c/src/lib/libbsp/powerpc/ss555) should be either actual
board-specific code, or irreducible boilerplate.

I recommend you copy the ss555 directory and edit it to suit your needs.
