These changes are required to support PCIe devices that have huge BAR. v3 changes: 1. Explicitly mention in change log that: Each PCIe node in dts will have 1 32-bit non-prefetchable memory window and 1 64-bit prefetchable memory window. v2 changes: 1. Separate device-tree changes and driver changes into different patches 2. Explicitly define new large window as 64-bit prefetchable in dts. 3. Use IORESOURCE_PREFETCH flag to determine which PCIe controller register to be used to configure the memory ranges. arch/arm64/boot/dts/apm/apm-storm.dtsi | 23 ++++++++++++++--------- drivers/pci/host/pci-xgene.c | 12 ++++++++++-- 2 files changed, 24 insertions(+), 11 deletions(-) -- 1.9.1
