Extends the mii_dev structure to participate in a full-blown MDIO and PHY driver scheme. The mii_dev structure and miiphy calls are modified in such a way to allow the original mii command and miiphy infrastructure to work as before, but also to support a new set of APIs which allow (among other things) sharing of PHY driver code and 10G support

The basic design is similar to PHY Lib from Linux, but simplified for U-Boot's network and driver infrastructure.
Did you copy any actual code? If so, please make sure to identify the exact origin; see http://www.denx.de/wiki/view/U-Boot/Patches#Attributing_Code_Copyrights_Sign
