...yes, very good catch and absolutely true ….
you can avoid the rainbow-hang in u-boot 2020.10 with a brutal :
-------$ rm /Volumes/MSDOSBOOT/armstub8-gic.bin-------
modern firmware of https://github.com/raspberrypi/firmware/tree/master/boot 
should no longer depend on armstub8(-gic).bin,
that’s why it is removed in  ubuntu.

but for some reason we will now panic in :
—
Starting CPU 1 (1)
panic: No PSCI/SMCCC call function set
—
the reason seems to be here  :
