Older, U-Boot 2022.04 (Oct 02 2022 - 23:00:31 +0000)

It's possible the boot would have completed on its own had
I kept my mitts off the keyboard. The loader boot delay
countdown ticks seems slow by about 10X. That might
explain the 
init_uart_clock=3000000
in the old config.txt. 

I should have said earlier that this particular Pi3 was
configured to boot direct from USB, without a microSD
card, but never would. I ended up using a bootcode.bin
file alone on the DOS partition. I should probably pull
the microSD card to see if the new config.txt changes
that behavior.

Thanks for writing!
