Actually now u-boot-dtb.img is a FIT image with a device tree wrapper. So need fix imx_usb to support both legacy and new image format.
This issue also affects the UUU tool as well.
Is there a fix for UUU?
[Frank Li] If follow up i.MX8MM method, uuu needn't change.
NXP software not enable SPL for this board, so I think UUU might not support it. But UUU support SPL + FIT for i.MX8MM, uuu might work for this board. I do not have time to check uuu side recently. Let me check whether others have time on this.
