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.

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.
