Please turn these messages into debug level.

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 _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
