Ah, ok.

Then I would ideally like to see this patch add the ITS block between
Distributor and Redistributors regions. I think it makes the most sense
for this version to match the GIC-600 layout.

I am also going to rework those two remaining gicv4-ish patches based
on my acquired understanding, to be sent out post v6.1.

And, I would like to switch the default CPU of sbsa-ref to "max" as
part of that platform versioning, now that is supported in TF-A
(from v2.5).
