Please turn these messages into debug level. They are too noisy to appear on every boot.

What is imx-mkimage? Why do you need a special tool and can't use the official mkimage one?

Sorry, but this README simply does not work.
All these required firmwares and imx-mkimage are really confusing. I am not able to get a bootable image by reading this README file.
Please improve the README so that a user can really make a bootable SD card by following the described step by step sequence.
That's what the README is for :-)
Thanks
