From: Shiraz Hashim shiraz.hashim@st.com
SPEAr310 and SPEAr320 Ethernet interfaces share same MDIO lines to control their respective phys. Currently there is a fixed configuration in which only a particular MAC can use the MDIO lines.
Call an arch specific function to take control of specific mdio lines at runtime.
