From: Shiraz Hashim<shiraz.has...@st.com>SPEAr310 and SPEAr320 Ethernet interfaces share same MDIO lines to control their respective phys. Currently their 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.
