Hello list,
inside the automatic U-Boot patch tracking system a new ticket [DNX#2007012542000021] was created:
<snip>
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.
