That sounds cool, welcome on board. The starting point would be this wiki
article about how to add a new target to the compiler, which would be
necessary for system_powerpc_freebsd and system_powerpc64_freebsd:

http://wiki.freepascal.org/Porting_Free_Pascal

Which is slightly obsolete, and it doesn't really cover the RTL part, but
the main points are still the same to do the first steps. Of course, you
have to take care that the compiler and libs sort of already works on
FreeBSD, so only implement the CPU specific parts, or include
PowerPC/PowerPC64 into the lists where necessary. It's nothing rocket
science. If you have specific questions, feel free to ask, also feel free
to send patches for review and upstream inclusion.

Cheers,
