This patch converts the Marvell MV643XX ethernet driver to use the
Marvell Orion MDIO driver. As a result, PowerPC and ARM platforms
registering the Marvell MV643XX ethernet driver are also updated to
register a Marvell Orion MDIO driver. This driver voluntarily overlaps
with the Marvell Ethernet shared registers because it will use a subset
of this shared register (shared_base + 0x4 - shared_base + 0x84). The
Ethernet driver is also updated to look up for a PHY device using the
Orion MDIO bus driver.

Can you finish off this job by making the mv643xx_eth driver accept
the standard phy-handle OF property instead of using a phy address?

I can certainly do that, at the same time we need to continue supporting the 
"old" platform device style registration without breaking them (PowerPC in 
particular, and the hopefully yet to be converted orion5x). So the phy_scan() 
as I modified it will probably still be there.

Ie the end result should be something like:

                smi0: mdio@72000 {
                        device_type = "mdio";
                        compatible = "marvell,orion-mdio";
                        reg = <0x72004 0x4>;

                        #address-cells = <1>;
                        #size-cells = <0>;
                        PHY1: ethernet-phy@1 {
                                reg = <1>;
                                device_type = "ethernet-phy";
                                phy-id = <0x01410e90>;
                        };
                };

                egiga0 {
                        device_type = "network";
                        compatible = "marvell,mv643xx-eth";
                        reg = <0x72000 0x4000>;
                        port_number = <0>;
                        phy-handle = <&PHY1>;
                        interrupts = <11>;
                        local-mac-address = [000000000002];  /* Filled by
