From: Martin Blumenstingl <martin.blumenstingl@xxxxxxxxxxxxxx> The CPU port has to specify a phy-mode and either a phy or a fixed-link. Since GSWIP is connected using a SoC internal protocol there's no PHY involved. Add phy-mode = "internal" and a fixed-link to describe the communication between the PMAC (Ethernet controller) and GSWIP switch.
