   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.

  52           PCIe host controllers, such as the one emulated by QEMU.

  68           Say Y here if you want to enable PCIe controller support on
  69           Renesas RCar Gen2 SoCs. The PCIe controller on RCar Gen2 is

  74         depends on SANDBOX && DM_PCI
  75         help
  76           Support PCI on sandbox, as an emulated bus. This permits testing of
  77           PCI feature such as bus scanning, device configuration and device
  78           access. The available (emulated) devices are defined statically in
  79           the device tree but the normal PCI scan technique is used to find

  89           3 root ports with a total of 6 lanes and Tegra124 has 2 root ports
