That was the case I seen, yes.

Have old kernel running, dtbs building. Apply a patch. It starts
behaving weird. You do make clean... but you still get old dtbs.

(It would be nice if make socfpga_cyclone5.dtb would magically remove
all the dtbs from old location; make dtbs does that if I understand
stuff correctly).

Thanks,
