Ramdisk image is partially overwritten while loading the
Device Tree: Ramdisk ends at 0x007ff17e, Device Tree starts
at 0x007fa000. You probably need to update U-Boot to recent
version to solve this issue.

Ramdisk decompression failed, it's expected as ramdisk was
overwritten by DTB while booting.

Try to update U-Boot to v1.3.4.
