@mhamrick mentions having done it here:

Starting Tiny OS Development With HiFive1

i actually did this for a customer. (code that runs in RAM and writes FLASH.) Megan describes the fespi driver in this post from way back when: i was also able to run TINY BASIC on the HiFive1, but still trying to figure out how to modify it to allow me to do GPIO twiddling.

Don’t know if there’s source available, but that thread might give some more information.
