please contact Atmel support for their software. This is the mainline
U-Boot Mailinglist, we can only give support fort mainline U-Boot. But
let's see if I can help you ...

The 'Bad Data CRC' may be some corrupted image or code. It may fail in
2015.01 due to U-Boot relocation, uImage extraction or some other
mechanism which may has changed since 2012.10 (plus unknown patches). So
a bit more information about what exactly is failing and some
surroundings required: Which board? What type of image(s)? What was the
command failing? Which addresses used and how many RAM is available? Any
constraints regarding reserved memory? ....

I'll verify that sama5d3xek is loading ramdisk larger than 4MiB with
mainline U-Boot and post the results.
