In MPC838 i have following clarifications,

1)  eTSEC IO Supply for RGMII will be 2.5V as per the datasheet but in reference design  LVDD1(NVDDF1) is connected to 2.5V and LVDD2(NVDDC1) is connected to 3.3V but i am thinking LVDD2 also needs to connect 2.5V so kindly clarify this.

2) for MPC8308 it is required to use VTT for DDR? in reference design they have not included this section and i am using only one device with 128MB density having organization 64MX16 so kindly clarify the VTT requirement.
