currently i use the rfb dts for r3 in uboot: arch/arm/dts/mt7986a-sd-rfb.dts

this file in upstream uboot has no partitions defined

https://source.denx.de/u-boot/u-boot/-/blob/master/arch/arm/dts/mt7986a-sd-rfb.dts#L144

but i added them there too and i wrote content by offsets to main device (not to partitions).

https://github.com/frank-w/u-boot/blob/2023-04-bpi/arch/arm/dts/mt7986a-sd-rfb.dts#L154

so yes basicly it needs to be send there too, maybe as additional dts.
