+Subject: [PATCH 2/2] arm64: tegra: Re-order PCIe aperture mappings to support
+ ACPI boot
+
+Re-order Tegra194's PCIe aperture mappings to have IO window moved to
+64-bit aperture and have the entire 32-bit aperture used for accessing
+the configuration space. This makes it to use the entire 32MB of the 32-bit
+aperture for ECAM purpose while booting through ACPI.
