[Sigh]

I already answered this question more than once. I guess it doesn't
hurt to answer it again: It helps the users. Please, don't forget
about them.

If I, as an embedded developer, design my board to work with kernel
version N and a given DTB, then I can upgrade to any kernel version
M (where M > N) using the *same* DTB, and it still works.

Thanks,
Richard
