Also, please map the whole region for the
redistributor as we have on the DT side (4 64kB pages for VLPIS capable
redistributors).

Hanjun, is it something you had problem with?

Yes, for D02, it use 3 64kB pages for GICv4, it removed the reserved
page. In DT case, it has "stride" binding so it can support no standard
cases, seems that we can introduce "stride" for ACPI too.

Thanks
Hanjun
