The bad version error is because you are running a version 16 blob and you need a version 17 blob to allow modifications. David Gibson has an intention of upconverting a v16 to v17 as part of libfdt, but neither of us has gotten around to doing it yet.
In that case, "libfdt: FDT_ERR_BADVERSION" is a really useless error message. Please change it to something like, "Cannot modify this version (v16) of the device tree".
Now that we support multiple version of the device tree, it is very important that error message are clear. On a working system, it's unlikely people will update their device tree. They'll just update the kernel and U-Boot, and so people using older versions of the device tree need to be told very clearly what they can and can't do.
