uCLinux SGMII and SFP modules

Hi All,

We have a custom Cyclone IV board with an SFP interfaced to the FPGA via SGMII on a standard Altera TSE. We also have an opencores i2c bus to control the moddef pins.

We have a uClinux build that works with the same PCB but with a standard GMII/MDIO interfaces to a Micrel PHY. This works fine.

Can anyone give me any assistance in what would be required to set up the drivers etc for SGMII rather than GMII?

If it helps I am using the device tree for kernel config.

Many thanks

Vern
