Interfacing Cyclone IV FPGA with Marvell PHY 88E1111 using SGMII

Hi I am using the cyclone IV with SGMII interfaced with Marvell PHY 88E1111. So what are the registers to be configured in the phy and how can I configure it for SGMII.

If you have a look at the marvell_cfg_sgmii() I talked about you should see what the driver does to configure the marvel chip into SGMII mode.

As it is a custom board you probably have the 88E1111 datasheet too, you should find a list of the PHY MDIO registers there with indications on how to set it up in SGMII mode.
