That looks like a royal pain. Again, I think it'd be much simpler (but
not less code, unfortunately) to do this on a per-resource basis. That
way these low-level firmware drivers in the kernel can stay trivial,
keeping the real complexity where they belong: in hardware-specific
drivers such as DRM/KMS.
