uuu using u-boot-with-spl.imx

[Michael Nazzareno Trimarchi]

Hi Fabio and Marek

Trying to understand the reason why I can boot using imx_usb loader
and not the uuu tool

If I do:

./imx_usb SPL
./imx_usb u-boot-dtb.img

It works

If I tried with the combined image using uuu it does not work like that.
