Leah, thanks for the great news!
GNU Libreboot team, good work! :-D

I saw a few AMD motherboards on the list.
So it really got me motivated and
I opened a discussion on AMD developers forum entitled:
When will XDMA compatible motherboards support Libreboot and-or RYF?

For clarification XDMA are motherboards which have multiple PCIe3
slots, and allow for multiple GPU's to run in parallel together.

It allows for vast amount of cheap processing power to be used.
Remember that a GPU FLOP is 100 times cheaper than a CPU FLOP.
1 GPU GFLOP ~= $0.05, 1 CPU GFLOP ~= $5.

I'm hoping that you could comment in support of either AMD helping to
make Libreboot RYF compatible software stacks, or XDMA in particular.

Feel free to note the Libreboot versions of AMD hardware that are
available, as well as what would be required to make them top notch.
As well as anything that might be necessary to make AMD RYF compliant.

here is the forum thread:
