Unfortunately, you'll have to communicate this in some other way to
Linux. I also had this problem and submitted a patch for it. In the
replies there were some suggestions on how to handle this:

Unfortunately, there is no standard way of doing this on ARM. Some
people want to introduce PowerPC-style device trees on ARM as well,
where this is handled in a generic way, but that hasn't been done yet
and requires changes on both the Linux-side and U-boot.


So I believe this kind of patches will not be accepted, unfortunately.
If you depend on the behavior, you can obviously keep the patch in your
own tree.
