Added to config.txt as well.
In general there isn't much additional output from u-boot.
On a successful try I see what begins as (I think) bootcode.bin output:
.....

Failed attempts are more terse:

I imagined u-boot would be more talkative,
similar to the MESS..... output from bootcode.bin
The output from make reports
===> Applying extra patch patches for u-boot-rpi-arm64-2022.04_1 from /usr/ports/sysutils/u-boot-rpi-arm64/files/
No such line 209 in input file, ignoring
Strangely, it doesn't report which patch didn't work.
The directory contains
patch-common_usb.c patch-common_usb__storage.c patch-lib_efi__loader_efi__console.c
patch-common_usb__hub.c patch-include_configs_rpi.h rpi_arm64_fragment
No idea whether it matters.
Thanks for reading,
