1 * ThunderX PCI host controller for pass-1.x silicon 2 3 Firmware-initialized PCI host controller to on-chip devices found on 4 some Cavium ThunderX processors. These devices have ECAM-based config 5 access, but the BARs are all at fixed addresses. We handle the fixed 6 addresses by synthesizing Enhanced Allocation (EA) capabilities for 7 these devices. 8 9 The properties and their meanings are identical to those described in 10 host-generic-pci.txt except as listed below. 11 12 Properties of the host controller node that differ from 13 host-generic-pci.txt: 14 15 - compatible : Must be "cavium,pci-host-thunder-ecam" 16 17 Example: 18 19 pcie@84b000000000 { 20 compatible = "cavium,pci-host-thunder-ecam"; 21 device_type = "pci"; 22 msi-parent = <&its>; 23 msi-map = <0 &its 0x30000 0x10000>; 24 bus-range = <0 31>; 25 #size-cells = <2>; 26 #address-cells = <3>; 27 #stream-id-cells = <1>; 28 reg = <0x84b0 0x00000000 0 0x02000000>; /* Configuration space */ 29 ranges = <0x03000000 0x8180 0x00000000 0x8180 0x00000000 0x80 0x00000000>; /* mem ranges */ 30 };
