The 8GB model lacks the firmware EEPROM for the USB controller,
instead it is part of the GPU firmware and gets pushed to the
USB controller.

A serial console is usually easier to follow.

RPI4 just uses start4.elf/fixup4.dat. The cd/db/x files are
cut-down (disabled GPU features), debug and extended (needed for
camera) variants.

bootcode.bin isn't used, the code is in an EEPROM instead.

Add a serial console. A line 'uart_2ndstage=1' in config.txt
will make the firmware verbose.

I'll fetch arm64.img.gz from nycdn to see what is missing..
