1fff8624c2
Intended for a use-case that needs to avoid using _TRA ACPI method. This overlay changes the PCIe controller non-prefetchable regions to: C5: 0x28000000 - 0x3b7fffff (size 312 MB) C4: 0x3b800000 - 0x3dbfffff (size 36 MB) C1: 0x3dc00000 - 0x3fffffff (size 36 MB) The controller corresponding to the Concord PCIe slot is also moved to domain 0.
