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).
