None of the HPS I/Os supports 3 V mode, while SD/MMC cards must operate at 3 V at power on. eMMC devices can operate at 1.8 V at power on.
Note: SD cards power up at 3 V. To support SD, your design must include a level shifter between the SD card and the HPS SD/MMC interface.

107 When the drvsel bitfield in the sdmmc register is set to 3 (in the system manager) and the reference clock (sdmmc_clk) is 200 MHz for example, the output delay time is 7.5 to 10.5 ns.
108 When the smplsel bitfield in the sdmmc register is set to 2 (in the system manager) and the reference clock (sdmmc_clk) is 200 MHz for example, the setup time is 1 ns and the hold time is 5.5 ns.
