thanks for the link.
No surprise what we`ll find when we click the issue-tab on that website :
https://github.com/raspberrypi/firmware/issues/1518

Following the the last comment from u-boot-hacker Nicolas Saenz Julienne :
https://github.com/raspberrypi/firmware/issues/1518#issuecomment-750910297 :
..
IIUC you are also triggering an xHC firmware load through the mailbox interface. AFAIK this mailbox interface expects a configured PCIe bus honoring whatever is in DT.
..
Whereas edkII doesn’t expose PCIe afaik, Rob Crowston doesn’t have problems with the mailbox :

Yes, and
thanks to Andy McClements we exactly know(at the moment) , what to pickup and what not.

So the Nicolas Saenz- hack is included in https://reviews.freebsd.org/D26853 and fell in love with Rob`s mbox-hack :-) ..as far as I understand..

Everything else , I guess, what Nicolas Saenz is preparing for upcoming u-boot versions should be handled later with the next fbsd-u-boot-port
