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.

Try a few more -v options to miitool, it will then print the register
dumps. You could compare them to a working Linux. Otherwise it also
might be the interaction of the ethernet driver with the switch driver.
The barebox version of the switch driver is very basic, it might well be
that there's something missing.
Sorry, it's hard to be more specific here...
