Fixing those issues requires further discussion. Frankly, right now I
really have no idea which way should I go. The /reserved-ranges node seems
to be easy to match particular reserved memory region with a given device.
I'm also not really convinced if it makes sense to add a code for finding
and matching a reserved memory region to every device driver, which might
need it. I would really like to get some more feedback on the Ben's
comment.

In any case, the code will also change significantly, so I assume that the
best, what can be done now is to revert the current version and start from
the scratch with a new, complete proposal.

Yes, let's do that. I will try to help. It shouldn't be that a big deal.

I think we can get the concerns sorted quickly. I'm at meetings all
day today in SJC, but I'll take a look at it this evening. I'll be in
Edinburgh. We're holding an ARM summit at the same time so a bunch of
affected ARM folks will be there.

After reading through the entirety of the other thread, I think this can
be fixed. My preference would be to fix in now rather than waiting
another cycle. If you haven't sent the revert yet then please hold off
for a bit (I can't tell at the moment since I'm currently on an airplane
and I didn't update my tree before leaving the ground).
