[U-Boot] How to access non Ethernet PHY from U-boot

Hi, I have a CFP module which is interfaced on the MDIO bus of NXP MPC8308 controller. I want to access the CFP module registers from u-boot using 'mii' command, as of now the 'mii info' is not listing this device which has address '6' in the MDIO bus.

In the case of Ethernet PHY I would go to drivers/net/tsec.c and add the structure info in 'struct phy_info *phy_info[]' for the probe function to detect it.

A CFP module follows MDIO interface definition in IEEE 802.3 Clause 45, http://www.cfp-msa.org/Documents/CFP_MSA_MIS_V2p2r06a.pdf

Any help is appreciated. Greg
