In boot 2020.10 the whole armstubs-stuff should or has to be removed when using modern firmware
so 
….MESS:00:00:08.221028:0: Loading ‚armstub8-gic.bin' to 0x0 size 0x1700...
will result in a hdmi-rainbow - screen - hang ( or console-hang)(`ve tested it with your removed device_tree_address=0x4000 also(still hangs))
If you want to test I`ve uploaded the u-boot2020.10 to spare you some compile-time on your nice weekend ;-) :
https://wiki.freebsd.org/arm/Raspberry%20Pi#RPI4
(Best to test directly boot from SSD because that’s the purpose to upgrade u-boot)
