   CFG_POCMR2_MASK_ATTRIB: (MPC826x only)
                Overrides the default PCI memory map in cpu/mpc8260/pci.c if set.
 
+- CONFIG_ETHER_ON_FEC[12]
+               Define to enable FEC[12] on a 8xx series processor.
+
+- CONFIG_FEC[12]_PHY
+               Define to the hardcoded PHY address which corresponds
+               to the given FEC.
+
+               i.e. 
+                  #define CONFIG_FEC1_PHY 4 
+               means that the PHY with address 4 is connected to FEC1
+
+               When set to -1, means to probe for first available.
+
+- CONFIG_FEC[12]_PHY_NORXERR
+               The PHY does not have a RXERR line (RMII only).
+               (so program the FEC to ignore it).
+
+- CONFIG_RMII
+               Enable RMII mode for all FECs.
+               Note that this is a global option, we can't
+               have one FEC in standard MII mode and another in RMII mode.
