Sjoerd Simons submitted the original patch (0001) to carry over some firmware-provided properties into the loaded device tree. This did not fix an issue with Raspberry Pi 400 rev 1.1 boards which would not be able to find the ethernet PHY device at the address specified by the kernel device tree.
Patch 0002 expands on Sjoerd's design to also carry over the real ethernet PHY address, enabling the kernel to find and enable a working ethernet on pi 400 rev 1.1 boards.
