/*
* 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.
