Hello, I have an armada 370 box, and it's using the marvell 88e6171r switch, I'm trying to port barebox to this box. But the mv88e6xxx driver not working properly on my box, below is the miitool output: barebox@Marvell Armada 370/XP:/ miitool mdio0-phy15: f1072004.mdio@72004.of: powerdown, no link mdio0-phy16: f1072004.mdio@72004.of: 10 Mbit, half duplex, no link mdio1-phy00: f1072004.mdio@72004:switch0@0.of: powerdown, no link mdio1-phy01: f1072004.mdio@72004:switch0@0.of: powerdown, no link mdio1-phy02: f1072004.mdio@72004:switch0@0.of: powerdown, no link mdio1-phy03: f1072004.mdio@72004:switch0@0.of: powerdown, no link mdio1-phy04: f1072004.mdio@72004:switch0@0.of: powerdown, no link The attachment is the device tree of my box, the switch is working properly on kernel 4.19 and above. Can you give some suggestions for me? Thanks. Regards.
