Those two boards connect a microSD card slot to the MMC0 controller. Add the dummy regulator and enable MMC0 to allow accessing the SD card. The BananaPi M64 has an on-board eMMC chip connected to the MMC2 controller, but the existing MMC driver does not support this properly yet, so keep this one disabled for now.
