Some Raspberry Pi 400 boards, specifically rev 1.1, have a different address for the ethernet PHY device than what is provided by the kernel DTB. The correct address is provided by the firmware, so we should carry it over into the loaded device tree so that ethernet works on such boards.
Minor nit: this should be properly wrapped.
Yes, I did end up resending the patch a few days later with proper formatting and superseding this series. I'm very sorry for the confusion.
Resent on the 19th Aug.: https://patchwork.ozlabs.org/project/uboot/list/?series=314524
No change apart from the formatting of the commit messages.
