[U-Boot] [PATCH 21/21] arm: imx: add i.MX6ULL 14x14 EVK board support

Peng Fan van.freenix at gmail.com
Thu Aug 11 08:02:57 CEST 2016


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:
