SGMII mode initialization sequence is very similar to TBI mode initialization. Additional initialization is
required for the SerDes. An example of SGMII mode initialization sequence is shown in

SGMII Interface Support
MPC8313E PowerQUICC™ II Pro Integrated Processor Family Reference Manual, Rev. 2
SGMII mode utilizes the internal TBI PHY. The internal TBI PHY only
auto-negotiates at 1 Gbps. However, 10 Mbps and 100 Mbps speeds are
supported in SGMII mode. It is recommended that the external PHY inform
the MAC if the desired link speed is not 1 Gbps. Software can perform MII
management cycles to determine the external PHY link speed and program
ECNTRL and MACCFG2 accordingly.
