@tymcauley can you sign the Linux Foundation CLA? We recently switched to it so that we can finish the process of Chisel being an official ChipsAlliance project.

i dont think we should have changed Coerced to Child in that one part.

@jackkoenig sounds like there might be a bit of a delay in getting that sorted out on my company's end. I'll let you know when I've got an ETA, but we might not be able to actually land this for a bit.
