ARM should have done this for their 'hidden' boot partitions years ago. Glad to see this being done in riscv land.

One question, though, is that are these hifive specific, or something more general that we've only seen on hifive so far...

So far they are hifive-specific. Hopefully this scheme will be adopted more widely, but if it ends up that different vendors use different IDs or layouts it will just make the whole situation messier, at least from the POV of providing release images.
