Hi Ben,

Given a week has passed with the absence of any feedback
with respect to SRIO on 64 bit, are you OK with applying the
below patch[1] pretty much as-is?

It can't hurt, I'll put it in. That's normally Kumar's side of things
but then with him leaving FSL things are a bit in flux right now.

Cheers,
Ben.

Thanks,
Paul.

The following are seen while using the corenet64_smp_defconfig:

A quick inspection of the code leaves one with the impression
that it was not explicitly written with 64 bit support in mind,
so just block that as a possible config selection for now.

 but at least it will give the issue some visibility to the right ppl.]
