True. The Leap 42.2 version of u-boot-rpi3 did not enable support for "fdt apply", but the Tumbleweed version does, and in Base:System:Staging I have now enabled that feature for all boards and am waiting for anyone to complain. :) The Wiki links to overlay file examples in my GitHub repo for several expansion boards as inspiration. For our dtbs I have updated packaging branch, but it hasn't been merged into master yet, so I am testing a branch; without -@ full target-path needs to be used, and phandle references won't work beyond the local file, making pinctrl and gpio usage somewhat hard. -> upstream discussion and patches The older alternative of using individual "fdt" commands in U-Boot, that could be used in Leap 42.2, is still documented for some expansion boards, but may still have an endianness bug for phandles in Leap 42.2.
