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 : https://github.com/freebsd/freebsd-src/blob/098dbd7ff7f3da9dda03802cdb2d8755f816eada/sys/arm/broadcom/bcm2835/bcm2838_xhci.c#L169 > Am 04.01.2021 um 09:35 schrieb Mark Millard via freebsd-arm <[email protected]>: > >> The Raspberry Pi folks warn against picking up firmware from >> Master unless requested to by them. > 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 Regards K. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-arm To unsubscribe, send any mail to "[email protected]"
