I still don't like the addition of another CPU, but for the sake of
running older kernels (which seems to have a use-case in your case) I am
OK with this.
Maybe it's worth adding a comment which states that this list is
"closed" and just provided to support older kernels?
So that other SoCs don't get funny ideas... ;-)
Cheers,
