I do observe another issue - one of my "factory" board setup is not
using (till now) OF_CONFIG.

Without u-boot.img being a FitImage wrapped, the imx_usb_loader works
correctly (with current mainline).

After this change I do see the issue with imx_usb_loader.
Unfortunately, applying this patch doesn't help.

I will investigate this issue further tomorrow.
