On platforms with Plane_Control registers (Broxton/Skylake+) we can use X and Y tiled framebuffers for scanout (older platforms support X tiling only). As our main use case is 90° rotation with Y tiled framebuffers, we implement it for the newer platforms only for now. We also set up a fence register for linear access to the tiled frame- buffer through the aperture.
