Yeh, for me it prevents the following build lines appearing every time: DTC arch/metag/boot/dts/tz1090_01sp.dtb but it still does these every time: DTB arch/metag/boot/dts/tz1090_01sp.dtb.S AS arch/metag/boot/dts/tz1090_01sp.dtb.o Adding dtbs o targets actually didn't seem to be necessary with $(dtb-y) added.
