...yes, very good catch and absolutely true =E2=80=A6.
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=20
should no longer depend on armstub8(-gic).bin,
that=E2=80=99s why it is removed in  ubuntu.

but for some reason we will now panic in :
=E2=80=94
Starting CPU 1 (1)
panic: No PSCI/SMCCC call function set
=E2=80=94
the reason seems to be here  :
