Are you suggesting to then merge this with testcases.dtb to get static_test.dtb or keep two output files (static_test.dtb from testcases.dtb + overlays and static_test2.dtb from overlay_base.dtb and overlay.dtb) ? Asking because as I mentioned earlier, overlay_base.dtb doesn't have __overlay__ property for its nodes and we can't apply that to testcases.dtb using fdtoverlay. > Yes, overlay_base_base is a terrible name.
