If the following interfaces (SRIO, PCIE, GbE, Hyperlink, TSIP, EMIF16, SPI, Timer0, 1, UART CTS and RTS) are not used in the hardware design, how should they be terminated? Not connected or terminated to ground or other voltages

Thanks for directing. The answer is mainly left floating, or pulled low or high to reduce leakage current for some of the interfaces.
