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.

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.

29config PCI_AARDVARK
30	bool "Enable Aardvark PCIe driver"
31	default n
32	depends on DM_PCI
33	depends on ARMADA_3700
34	help
35	  Say Y here if you want to enable PCIe controller support on
36	  Armada37x0 SoCs. The PCIe controller on Armada37x0 is based on
37	  Aardvark hardware.
38
39config PCI_PNP
40	bool "Enable Plug & Play support for PCI"
41	depends on PCI || DM_PCI
42	default y
43	help
44	  Enable PCI memory and I/O space resource allocation and assignment.
45
46config PCIE_ASPEED
47	bool "Enable Aspeed PCIe driver"
48	depends on DM_PCI
49	depends on ARCH_ASPEED
50	help
51	  Say Y here if you want to enable PCIe controller support on
52          Aspeed SoCs.
53
54config PCIE_ECAM_GENERIC
55	bool "Generic ECAM-based PCI host controller support"
56	default n
57	depends on DM_PCI
58	help
59	  Say Y here if you want to enable support for generic ECAM-based
60	  PCIe host controllers, such as the one emulated by QEMU.
61
62config PCIE_DW_MVEBU
63	bool "Enable Armada-8K PCIe driver (DesignWare core)"
64	depends on DM_PCI
65	depends on ARMADA_8K
66	help
67	  Say Y here if you want to enable PCIe controller support on
68	  Armada-8K SoCs. The PCIe controller on Armada-8K is based on
69	  DesignWare hardware.
70
71config PCI_RCAR_GEN2
72	bool "Renesas RCar Gen2 PCIe driver"
73	depends on DM_PCI
74	depends on RCAR_32
75	help
76	  Say Y here if you want to enable PCIe controller support on
77	  Renesas RCar Gen2 SoCs. The PCIe controller on RCar Gen2 is
78	  also used to access EHCI USB controller on the SoC.
79
80config PCI_SANDBOX
81	bool "Sandbox PCI support"
82	depends on SANDBOX && DM_PCI
83	help
84	  Support PCI on sandbox, as an emulated bus. This permits testing of
85	  PCI feature such as bus scanning, device configuration and device
86	  access. The available (emulated) devices are defined statically in
87	  the device tree but the normal PCI scan technique is used to find
88	  then.
89
90config PCI_TEGRA
91	bool "Tegra PCI support"
92	depends on TEGRA
93	depends on (TEGRA186 && POWER_DOMAIN) || (!TEGRA186)
94	help
95	  Enable support for the PCIe controller found on some generations of
96	  Tegra. Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has
97	  3 root ports with a total of 6 lanes and Tegra124 has 2 root ports
98	  with a total of 5 lanes. Some boards require this for Ethernet
99	  support to work (e.g. beaver, jetson-tk1).
100
101config PCI_XILINX
102	bool "Xilinx AXI Bridge for PCI Express"
103	depends on DM_PCI
104	help
105	  Enable support for the Xilinx AXI bridge for PCI express, an IP block
106	  which can be used on some generations of Xilinx FPGAs.
107
108config PCIE_LAYERSCAPE
109	bool "Layerscape PCIe support"
110	depends on DM_PCI
111	help
112	  Support Layerscape PCIe. The Layerscape SoC may have one or several
113	  PCIe controllers. The PCIe may works in RC or EP mode according to
114	  RCW[HOST_AGT_PEX] setting.
115
116config PCIE_INTEL_FPGA
117	bool "Intel FPGA PCIe support"
118	depends on DM_PCI
119	help
120	  Say Y here if you want to enable PCIe controller support on Intel
121	  FPGA, example Stratix 10.
122
123config PCI_MVEBU
124	bool "Enable Armada XP/38x PCIe driver"
125	depends on ARCH_MVEBU
