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. ..

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=20= Regards K.
