commit e703545db4687af73f3b30f69277b2ffa5a84f57
Author: Leonard Crestez <leo...@nx...>
Date:   Thu Apr 4 16:19:55 2019 +0300

    target/imx6u: Initial support
    
    Unlike the rest of imx6 the 6UL 6ULL 6ULZ chips are based on Cortex-A7
    which is at a different address so a custom script is required.
    
    Tested on imx6ull-14x14-evk
