(Missing signed-off-by.) I thought the idea with the sbsa-ref dtb was that it was really just a minimal provision of data to the firmware, not a real DTB, and that (as on real hardware) creating the DTB to pass to the next level of the guest code was the job of the guest firmware. Why do we need to provide a full GIC DTB node ? thanks -- PMM
