Dear Joe,

some dpmacs in armv8a based freescale layerscape SOCs can be configured via both serdes(sgmii, xfi, xlaui etc) bits and via EC*_PMUX(rgmii) bits in RCW. e.g. dpmac 17 and 18 in LX2160A can be configured as SGMII from serdes bits and as RGMII via EC1_PMUX/EC2_PMUX bits Now if a dpmac is enabled by serdes bits then it takes precedence over EC*_PMUX bits. i.e. in LX2160A if we select serdes protocol that configures dpmac17 as SGMII and set the EC1_PMUX as RGMII, then the dpmac is SGMII and not RGMII.
Therefore, in fsl_rgmii_init function of SOC, we will check if the dpmac is enabled or not? if it is (fsl_serdes_init has already enabled the dpmac), then don't enable it.
