Thanks to the help of Andrew Lunn, there is at least two known issues=20
with this patch version:

- we need to move up the mvmdio line in=20
drivers/net/ethernet/marvell/Makefile to make sure that configs having=20
both mvmdio and mv643xx_eth built-in get the probing order right
- the bus name used by mv643xx_eth is not the right now (orion-mdio.0 v=
s=20
expected orion-mdio) so the PHY device will not be found during=20
phy_connect()

I will fix these two issues in the next version of the patchset.
