Rev B (which is what I have been testing with) has the phy configured to respond with phy address 7, Rev C and newer appear to have changed to using 0 (not 100% sure on that though as I don't have access to the Marvell Datasheet).

I have a rev C here. Does anyone else have a rev B?

I also had some feedback that 0 is a broadcast address and 1 is the
correct phy address. I finally tested the device tree with phy address 1
and it looks like this works also. I'll update my build with this change
and let you know where the commit is.
