0x800 is MDIO_CTRL1_LPOWER. What is the other? It seems like a speed
selection bit?

The other is MDIO_PMA_CTRL1_SPEED1000. Will fix this in V2.

It seems odd to set a speed, and power it down. But i guess you have
blindly copied the reference code, so have no idea why?

I agree, absolutely no idea. I already asked the Marvell support for
any document describing the init sequence, but they couldn't help me.
So I have to stick to the reference code. At least I copied the comments
that were part of the init sequence, trying to give some meaning to it.
