Hi Arnd, Thank you for your reply. It is very helpful. :) I will set domain numbers for each struct hw_pci. > > > Current DT properties are as below: > > > > + pcie0@40000000 { > > + compatible = "samsung,exynos5440-pcie"; > > + reg = <0x40000000 0x4000 > > + 0x290000 0x1000 > > + 0x270000 0x1000 > > + 0x271000 0x40>; > > + interrupts = <0 20 0>, <0 21 0>, <0 22 0>; > > + #address-cells = <3>; > > + #size-cells = <2>; > > + device_type = "pci"; > > + ranges = <0x00000800 0 0x40000000 0x40000000 0 0x00200000 /* configuration space */ > > + 0x81000000 0 0 0x40200000 0 0x00004000 /* downstream I/O */ > > + 0x82000000 0 0 0x40204000 0 0x10000000>; /* non-prefetchable memory */ > > + }; > > An unrelated comment: your first "reg" field seems to overlap with part > of your configuration space.

According to the manual of Exynos PCIe, each memory space for Exynos PCIe can support 512MB, including I/O, CFG regions. Is there any problem when over 256MB boundary is used?
