10 * This file handles the board muxing between the Fman Ethernet MACs and
11 * the RGMII/SGMII/XGMII PHYs on a Freescale B4860 "Centaur". The SGMII
12 * PHYs are the two on-board 1Gb ports. There are no RGMII PHY on board.
13 * The 10Gb XGMII PHY is provided via the XAUI riser card. There is only
14 * one Fman device on B4860. The SERDES configuration is used to determine
15 * where the SGMII and XAUI cards exist, and also which Fman MACs are routed
16 * to which PHYs. So for a given Fman MAC, there is one and only PHY it
17 * connects to. MACs cannot be routed to PHYs dynamically. This configuration
18 * is done at boot time by reading SERDES protocol from RCW.
