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.

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.
