This series adds Ethernet support for the Raspberry Pi 4. The SoC
includes a "Broadcom Genet v5 MAC" IP, connected as a proper platform
device (no USB anymore!). Patch 1 provides a driver for that. There does
not seem to be publicly available documentation, so this is based on the
Linux driver, but stripped down to just provide what U-Boot needs.
Patch 2 fixes up the RPi4 memory map to accommodate the MMIO area the
MAC lives in, while patch 3 enables it in the respective defconfigs.
This version addresses the comments by the diligent reviewers and testers,
for a changelog see below.
To see the individual changes as patches, refer to [1].
Please have a look and test it, I hope this helps to simplify
development, as you spare the SD card and its slot from heavy swapping.
I dropped the Tested-by's, as there were changes in the code. Happy
to reapply them when people confirm that it still works for them.
Cheers,
Andre.
