I've done some further tests using the three previous RPI firmware 
releases to the current 20201227 release which does not work for me. 
Again, my environment is:

HW: RPi4b 8GB, late 2020 purchase, Sept 3rd EEPROM
OS: 
FreeBSD-13.0-CURRENT-arm64-aarch64-RPI-20201224-3cc0c0d66a0-255241.img.xz
Boot device: 128GB USB3 SSD

Releases tested:
https://github.com/raspberrypi/firmware/archive/1.20201022.zip
https://github.com/raspberrypi/firmware/archive/1.20201126.zip
https://github.com/raspberrypi/firmware/archive/1.20201201.zip

I am happy to say that, WITH PATCH D26853, all of these will 
successfully allow FreeBSD 20201224 to boot from USB SSD. Also that the 
vanilla 20201224 img (which I have checked includes the 20201201 
firmware) also works fine, WITH PATCH D26853.

I have also double-checked that the current firmware release, 20201227, 
with the patch, DOES NOT WORK. As previously reported, I just see a 
crash-loop in U-boot, if attempting to boot from USB SSD.

With hindsight it was unfortunate that I made the assumption that my 
initial problem was due to not having the latest firmware.

Test details, including dmesgs:
