If you don't necessarily care about getting exactly the pwm.scala that's in this repo, the easiest way is to go to the https://github.com/sifive/freedom repo, do a build for one of the FPGA targets and extract the pwm stuff from the huge generated .v file. If you ignore the TileLink stuff, you'll only need the module PWMTimer, which is half a kloc and has no dependencies.
