kbuild: determine base DTB by suffix
When using the -dtbs syntax, you need to list the base first, as follows: foo-dtbs := foo_base.dtb foo_overlay1.dtbo foo_overlay2.dtbo dtb-y := foo.dtb You cannot do this arrangement: foo-dtbs := foo_overlay1.dtbo foo_overlay2.dtbo foo_base.dtb This restriction comes from $(firstword ...) in the current implementation, but it is unneeded to rely on the order in the -dtbs syntax. Instead, you can simply determine the base by the suffix because the base (*.dtb) and overlays (*.dtbo) use different suffixes.
