Load u-boot via USB or UART on i.MX5, i.MX6, i.MX7, and Vybrid

This program boots an i.MX or Vybrid system using a copy of U-Boot transferred to the system over an OTG or UART connection. It can be used to “unbrick” a system which has a corrupted or missing copy of U-Boot in nonvolatile media such as nand flash or eeprom. i.MX systems use the OTG port, Vybrid systems use the UART port.

To use this, connect the OTG port of your i.MX board to a USB host port on your computer, power on the board, then run imx_usb where filename is the board-specific u-boot.imx file to boot with.
