Add i.MX6ULL EVK board support: Add device tree file, which is copied from NXP Linux. Enabled DM_MMC, DM_GPIO, DM_I2C, DM_SPI, PINCTRL, DM_REGULATOR. The uart iomux settings are still keeped in board file. Boot Log: U-Boot 2016.09-rc1-00366-gbb419ef-dirty (Aug 11 2016 - 13:08:58 +0800) CPU: Freescale i.MX6ULL rev1.0 at 396MHz CPU: Commercial temperature grade (0C to 95C) at 15C Reset cause: POR Model: Freescale i.MX6 ULL 14x14 EVK Board Board: MX6ULL 14x14 EVK DRAM: 512 MiB MMC: initialized IMX pinctrl driver FSL_SDHC: 0, FSL_SDHC: 1 In: serial Out: serial Err: serial Net: CPU Net Initialization Failed No ethernet found. Hit any key to stop autoboot: 0 => mmc dev 1 switch to partitions #0, OK mmc1 is current device Signed-off-by: Peng Fan <peng.fan@nxp.com> Cc: Stefano Babic <sbabic@denx.de>
