So per the documentation at
https://docs.u-boot-project.org/en/latest/develop/devicetree/control.html#resyncing-with-devicetree-rebasing
we only take modifications in dts/upstream that are strict cherry-pick's
from the upstream source. This needs to be done under arch/riscv/
instead, and you should split the additional changes in to a
-u-boot.dtsi suffixed file, so that it's easier to replace this with the
upstream file when ready. Thanks.
