arm: mx6: Add CCV xPress board support
This patch add support for the CCV xPress board which is equipped with the i.MX6UL. And provides the following interfaces: - 128MiB DDR - UART - I2C - eMMC (with booting) - Ethernet - USB This patch adds two build targets. One with and one without SPL. The non-SPL version is used for loading U-Boot via USB (imx_usb_loader). Signed-off-by: Stefan Roese <sr@denx.de> Cc: Fabio Estevam <fabio.estevam@nxp.com> Cc: Stefano Babic <sbabic@denx.de>
