Abort booting if the DTB version is incompatible
PATCH 1/1 Abort booting if the DTB version is incompatible
U-Boot only supports version 16 of the device tree file format, although some versions of the device tree compiler generate version 3 by default. With this patch, U-Boot now checks the version number and aborts the boot process if the version of the device tree passed on the bootm command line is not compatible.

Is there a differnce between your two submissions of the same (?) patch?

No. Sorry about that - I didn't intend to send it twice.
