the following `dmesg` of the 4GB is with the copied-over whole msdos-partition of the Original RPI-ubuntu-distribution
/ubuntu DOESN`T use the latest fw-files from rpi-github(which also fail with me to the hdmi-rainbow-screen),
Copying over „our“ old bcm2711-rpi-4-b.dtb, booted a bit more (until gpio or so afaik)….it`s all about DeviceTree 
and I guess Kyle Evans & friends  unfortunately will have more adjustment-work  in the brcm285..dtsi… for 2020.10
I unfortunately totally fail in my time-management but will tell more about the 8GB - VL805-videoCore-firmware-thing when finding time.. 
I didn’t yet apply kevans-patches, will test them it later..

It comes to boot problems short before xhci will be initialized from the DeviceTree
