1menuconfig PCI 2 bool "PCI support" 3 default y if PPC 4 help 5 Enable support for PCI (Peripheral Interconnect Bus), a type of bus 6 used on some devices to allow the CPU to communicate with its 7 peripherals. 8 9if PCI 10 11config DM_PCI 12 bool "Enable driver model for PCI" 13 depends on DM 14 help 15 Use driver model for PCI. Driver model is the new method for 16 orgnising devices in U-Boot. For PCI, driver model keeps track of 17 available PCI devices, allows scanning of PCI buses and provides 18 device configuration support. 19 20config DM_PCI_COMPAT 21 bool "Enable compatible functions for PCI" 22 depends on DM_PCI 23 help 24 Enable compatibility functions for PCI so that old code can be used 25 with CONFIG_DM_PCI enabled. This should be used as an interim 26 measure when porting a board to use driver model for PCI. Once the 27 board is fully supported, this option should be disabled. 28 29config PCI_PNP 30 bool "Enable Plug & Play support for PCI" 31 depends on PCI || DM_PCI 32 default y 33 help 34 Enable PCI memory and I/O space resource allocation and assignment. 35 36config PCIE_ECAM_GENERIC 37 bool "Generic ECAM-based PCI host controller support" 38 default n 39 depends on DM_PCI 40 help 41 Say Y here if you want to enable support for generic ECAM-based 42 PCIe host controllers, such as the one emulated by QEMU. 43 44config PCIE_DW_MVEBU 45 bool "Enable Armada-8K PCIe driver (DesignWare core)" 46 depends on DM_PCI 47 depends on ARMADA_8K 48 help 49 Say Y here if you want to enable PCIe controller support on 50 Armada-8K SoCs. The PCIe controller on Armada-8K is based on 51 DesignWare hardware. 52 53config PCI_SANDBOX 54 bool "Sandbox PCI support" 55 depends on SANDBOX && DM_PCI 56 help 57 Support PCI on sandbox, as an emulated bus. This permits testing of 58 PCI feature such as bus scanning, device configuration and device 59 access. The available (emulated) devices are defined statically in 60 the device tree but the normal PCI scan technique is used to find 61 then. 62 63config PCI_TEGRA 64 bool "Tegra PCI support" 65 depends on TEGRA 66 depends on (TEGRA186 && POWER_DOMAIN) || (!TEGRA186) 67 help 68 Enable support for the PCIe controller found on some generations of 69 Tegra. Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has 70 3 root ports with a total of 6 lanes and Tegra124 has 2 root ports 71 with a total of 5 lanes. Some boards require this for Ethernet 72 support to work (e.g. beaver, jetson-tk1). 73 74config PCI_XILINX 75 bool "Xilinx AXI Bridge for PCI Express" 76 depends on DM_PCI 77 help 78 Enable support for the Xilinx AXI bridge for PCI express, an IP block 79 which can be used on some generations of Xilinx FPGAs. 80 81config PCIE_LAYERSCAPE 82 bool "Layerscape PCIe support" 83 depends on DM_PCI 84 help 85 Support Layerscape PCIe. The Layerscape SoC may have one or several 86 PCIe controllers. The PCIe may works in RC or EP mode according to 87 RCW[HOST_AGT_PEX] setting. 88 89endif 90
