I created a branch on github, you can access it at https://github.com/sherrysun1/u-boot-imx.git.
It includes some patches which I tested for cdns3 driver on imx8qm/qxp, maybe useful to you.
By the way, I also add device tree bindings in doc/device-tree-bindings/usb/ at my branch in github, in case you need.
Feel free to let me know if any problems.

Best regards
