+ Selects fec_mxc.c to be compiled into u-boot.
+
+CONFIG_MII
+ Must be defined if CONFIG_FEC_MXC is defined.
+
+CONFIG_FEC_XCV_TYPE
+ Defaults to MII100 for 100 Base-tx.
+ RGMII selects 1000 Base-tx reduced pin count interface.
+ RMII selects 100 Base-tx reduced pin count interface.
+
+CONFIG_FEC_MXC_SWAP_PACKET
+ Forced on iff MX28.
+ Swaps the bytes order of all words(4 byte units) in the packet.

+
+CONFIG_PHYLIB
+ fec_mxc supports PHYLIB and should be used for new boards.
+
+CONFIG_FEC_MXC_NO_ANEG
+ Relevant only if PHYLIB not used. Skips auto-negotiation restart.

+CONFIG_FEC_MXC_PHYADDR
+ Optional, selects the exact phy address that should be connected
+ and function fecmxc_initialize will try to initialize it.
