/*
 * 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.
