Please reword: This is not a fix, but an enhancement.

This change is correct.

I don't know the uImage format very well. Can you give examples of what this
patch can bring compared to the raw binary format?

If this change is useful, it should probably be made for u-boot-with-spl.imx
too.

Best regards,
Benoît
