7 Enable support for PCI (Peripheral Interconnect Bus), a type of bus
8 used on some devices to allow the CPU to communicate with its
14 Use driver model for PCI. Driver model is the new method for
15 orgnising devices in U-Boot. For PCI, driver model keeps track of
16 available PCI devices, allows scanning of PCI buses and provides
17 device configuration support.
22 bool "Enable compatible functions for PCI"
25 Enable compatibility functions for PCI so that old code can be used
26 with CONFIG_DM_PCI enabled. This should be used as an interim
27 measure when porting a board to use driver model for PCI. Once the

66 being used as virtual address.

166 PCI feature such as bus scanning, device configuration and device
167 access. The available (emulated) devices are defined statically in
168 the device tree but the normal PCI scan technique is used to find
