menu "PCI" config DM_PCI bool "Enable driver mode for PCI" depends on DM 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. config PCI_SANDBOX bool "Sandbox PCI support" depends on SANDBOX && DM_PCI help 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. endmenu
