Enable support for PCI (Peripheral Interconnect Bus), a type of bus

used on some devices to allow the CPU to communicate with its

peripherals.

help
|
|
Use driver model for PCI. Driver model is the new method for
|
|
orgnising devices in U-Boot. For PCI, driver model keeps track of
|
|
available PCI devices, allows scanning of PCI buses and provides
|
|
device configuration support.

help
|
|
Enable compatibility functions for PCI so that old code can be used
|
|
with CONFIG_DM_PCI enabled. This should be used as an interim
|
|
measure when porting a board to use driver model for PCI. Once the
|
|
board is fully supported, this option should be disabled.

Support PCI on sandbox, as an emulated bus. This permits testing of
|
|
PCI feature such as bus scanning, device configuration and device
|
|
access. The available (emulated) devices are defined statically in

|
the device tree but the normal PCI scan technique is used to find

then.
