Sure, and it's been done: https://github.com/christinaa/rpi-open-firmware - but that doesn't involve ThreadX source, just some standard reverse engineering work. ThreadX is really the least interesting part of this whole operation in terms…

I guess you are thinking of this issue: https://github.com/christinaa/rpi-open-firmware/issues/37 Since then the project moved to a new maintainer (not me), who worked on it slowly but surely. They need new contributors though.
