Currently there are the following SoM flavors (SoM-Line): * N6310: SOM with i.MX6UL-2, 256MB RAM, 256MB SPI NAND * N6311: SOM with i.MX6UL-2, 512MB RAM, 512MB SPI NAND * N6411: SOM with i.MX6ULL, 512MB RAM, 512MB SPI NAND And the according evaluation boards (Board-Line): * N6310-S: Baseboard with SOM N6310, eMMC, display (optional), ... * N6311-S: Baseboard with SOM N6311, eMMC, display (optional), ... * N6411-S: Baseboard with SOM N6411, eMMC, display (optional), ... Currently U-Boot describes i.MX6UL and i.MX6ULL through separate config options at compile-time. Though the differences are so minor, that for the scope of these SoMs we just use a single defconfig that is compatible with both SoCs.
