Okay, I'm glad our goals aren't that far apart then. It would be helpful
to stop dragging the Raspberry Pi into this, though, since it isn't at
all relevant.

This isn't at all relevant. And that's exactly why I think it's good to
hide all the resource management behind firmware. That way it becomes
easy to support any SoC with any firmware.

The functionality that it provides is still very generic. And the
firmware interface is generic too. It is this abstraction that allows
it to be generic. You on the other hand seem to be arguing that by
making it abstract we've made it less generic.
Abstraction is about hiding details to capture commonality.
