Further on this, I have just done another test by replacing only:
bcm2711-rpi-4-b.dtb
on the FreeBSD 13.0-CURRENT 20201224 img, with the one from the RPI
firmware 20201227 release.
This **allows booting from USB**, which fails on the stock 20201224 img.
So it seems to me that patch D26853 **is not required**, if the upstream
file is now working OK.
HOWEVER, the 20201227 firmware release appears to introduce some other
problem, as already reported if ALL the files on the DOS partition are
replaced with those from 20201227, it results in a crash in U-boot.
To summarise then, on the hardware mentioned above:
1. Vanilla FreeBSD-13.0-CURRENT-arm64-aarch64-RPI-20201224
" starting USB...
Bus xhci_pci: probe failed, error -110
No working controllers found "
Result: disk boot fails, RPi attempts to net boot.
2. Vanilla FreeBSD-13.0-CURRENT-arm64-aarch64-RPI-20201224
+ REPLACE ONLY bcm2711-rpi-4-b.dtb with the version from the 20201227
release.
"starting USB...

Starting the controller

Result: disk boot succeeds
3. Vanilla FreeBSD-13.0-CURRENT-arm64-aarch64-RPI-20201224
+ REPLACE ALL FIRMWARE FILES with the versions from the 20201227
firmware release.
