RZ/G2UL SoM has both 64GB eMMC and microSD connected to SDHI0. Both these interfaces are mutually exclusive and the SD0 device selection is based on SW1[2] on SoM module. Set SW1[2] to position OFF for selecting eMMC Set SW1[2] to position ON for selecting microSD This patch enables eMMC on RZ/G2UL SMARC platform by default.
