This patch add support for the imx6dl based aristainetos board with following configuration: CPU: Freescale i.MX6DL rev1.1 at 792 MHz DRAM: 1 GiB NAND: 512 MiB MMC: FSL_SDHC: 0, FSL_SDHC: 1 SF: Detected N25Q128 with page size 256 Bytes, erase size 64 KiB, total 16 MiB As this board can used with 2 different display types, the differences between them are extracted into 2 DTS files, and the common settings are collected in a common file.
