The reason we need this is that we have the gig port on mgcoge3un connected using a back-to-back pair of PHYs. There are no magnetics and because of that the port has to be run with a fixd configuration and auto-negotiation must be disabled. In the default mode the egiga driver uses autoneg to determine port speed - which defaults to 1G (we need 100M full duplex). Add wait for the GPIO line connected to mgcoge3ne before starting mgcoge3un. A board specific ethernet present function was added, because on this board ethernet is always present. The BOCO FPGA access was enhanced and changed to use register definitions.
