There's a work in progress PRU library:

https://bitbucket.org/rpaulo/libpru

And a program to upload binaries to the PRU:

https://bitbucket.org/rpaulo/pructl

These don't have documentation yet and you have to build them yourself, but that should be straightforward.

You can use the assembler from ports: devel/pasm.
