Please address my upstream DT review and give it some more time before
adding DTs that cannot be picked to dts/upstream in U-Boot.

For the past two years the Rockchip platform has only allowed adding
arch and boards using DTs that come from dts/upstream. So please give a
good explanation why your arch/board cannot wait until that is the case
and need exception from this.

Please split patch 7/7 in two, one that add rv1103b arch support and a
second that add the omega4 board. Then please move the board DTs to the
patch that adds support for the omega4 board.

The soc u-boot.dtsi is better to add in the patch that add rv1103b arch
support, i.e. this patch should only include DTs and headers that is a
drop in replacement for future files that are expected to land in
dts/upstream.
