Thanks for keeping my patches tested!

This means I would need to patch the imx_usb.c source code, and do it in
a way that is not relocatable.

Actually I have another plan [1]: creating a ready-to-use config file
and document how to use it, without touching how imx_usb works now.
Unless I'm missing something from your e-mail, I find my way cleaner
and more complete.

Users who want to use this tool in a different way can still find the
original files in output/build/imx-usb-loader-*/ of course.
