Add initial Rex Pro i.mx6q board support. Ethernet, UART, USB, I2C, SPI, HDMI, Audio, and SDHC cards are working. Currently no mainline u-boot, so boot with cat zImage imx6q-rex-pro.dtb > zImage.dtb, then using mkimage create uImage Signed-off-by: Robert Nelson <robertcnelson@gmail.com> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
