+/*
+ * This file handles the board muxing between the Fman Ethernet MACs and
+ * the RGMII/SGMII/XGMII PHYs on a Freescale P5040 "Super Hydra" reference
+ * board. The RGMII PHYs are the two on-board 1Gb ports. The SGMII PHYs are
+ * provided by the standard Freescale four-port SGMII riser card. The 10Gb
+ * XGMII PHYs are provided via the XAUI riser card. The P5040 has 2 FMans
+ * and 5 1G interfaces and 10G interface per FMan. Based on the options in
+ * the RCW, we could have upto 3 SGMII cards and 1 XAUI card at a time.
+ *
+ * Muxing is handled via the PIXIS BRDCFG1 register. The EMI1 bits control
+ * muxing among the RGMII PHYs and the SGMII PHYs. The value for RGMII is
+ * always the same (0). The value for SGMII depends on which slot the riser is
+ * inserted in. The EMI2 bits control muxing for the the XGMII. Like SGMII,
+ * the value is based on which slot the XAUI is inserted in.
+ *
+ * The SERDES configuration is used to determine where the SGMII and XAUI cards
+ * exist, and also which Fman's MACs are routed to which PHYs. So for a given
+ * Fman MAC, there is one and only PHY it connects to. MACs cannot be routed
+ * to PHYs dynamically.
+ *
+ *
+ * This file also updates the device tree in three ways:
+ *
+ * 1) The status of each virtual MDIO node that is referenced by an Ethernet
+ * node is set to "okay".
+ *
+ * 2) The phy-handle property of each active Ethernet MAC node is set to the
+ * appropriate PHY node.
+ *
+ * 3) The "mux value" for each virtual MDIO node is set to the correct value,
+ * if necessary. Some virtual MDIO nodes do not have configurable mux
+ * values, so those values are hard-coded in the DTS. On the HYDRA board,
+ * the virtual MDIO node for the SGMII card needs to be updated.
+ *
+ * For all this to work, the device tree needs to have the following:
+ *
+ * 1) An alias for each PHY node that an Ethernet node could be routed to.
+ *
+ * 2) An alias for each real and virtual MDIO node that is disabled by default
+ * and might need to be enabled, and also might need to have its mux-value
+ * updated.
