   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.

  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.

  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.

  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.

  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.

  58           Say Y here if you want to enable PCIe controller support on
  59           Renesas RCar Gen2 SoCs. The PCIe controller on RCar Gen2 is
  60           also used to access EHCI USB controller on the SoC.

  64         depends on SANDBOX && DM_PCI
  65         help
  66           Support PCI on sandbox, as an emulated bus. This permits testing of
  67           PCI feature such as bus scanning, device configuration and device
  68           access. The available (emulated) devices are defined statically in
  69           the device tree but the normal PCI scan technique is used to find
  70           then.

  77           Enable support for the PCIe controller found on some generations of

  79           3 root ports with a total of 6 lanes and Tegra124 has 2 root ports
  80           with a total of 5 lanes. Some boards require this for Ethernet
  81           support to work (e.g. beaver, jetson-tk1).

  87           Enable support for the Xilinx AXI bridge for PCI express, an IP block

  94           Support Layerscape PCIe. The Layerscape SoC may have one or several
  95           PCIe controllers. The PCIe may works in RC or EP mode according to
