Good idea indeed. I just did that and executed "dtc -I fs /sys/firmware/devicetree/base“ in a quick RaspberryPiOS installation. See [1] for the corresponding output. Hopefully Ivan can do the same so that we can see if there are any differences that might explain why his u-boot patches are working for him while they does not for me.
