The changes are as following: 1. The new 87x and 88x series of processors have two FECs, and the new driver supports them both. 2. Another change in the 87x/88x series is support for the RMII (Reduced MII) interface. However numerous changes are needed to make it work since the PHYs are connected to the same lines. That means that you have to address them correctly over the MII interface. 3. We now correctly match the MII/RMII interface configuration to what the PHY reports. The following new defines are supported: CONFIG_ETHER_ON_FEC[12] Enable FEC on given FEC CONFIG_FEC[12]_PHY Assign PHY address to FEC. If -1 means probe. CONFIG_FEC[12]_PHY_NORXERR The PHY does not have a RXERR line (RMII only). CONFIG_RMII Enable RMII mode common for any activated FECs. For compatibility reasons the name of the first interface remains unchanged at 'FEC ETHERNET' while the second is name 'FEC2 ETHERNET'.
