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.

21 bool "Enable compatible functions for PCI"
22 depends on DM_PCI
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.

50 Support PCI on sandbox, as an emulated bus. This permits testing of
51 PCI feature such as bus scanning, device configuration and device
52 access. The available (emulated) devices are defined statically in
53 the device tree but the normal PCI scan technique is used to find
54 then.

61 Enable support for the PCIe controller found on some generations of
62 Tegra. Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has
63 3 root ports with a total of 6 lanes and Tegra124 has 2 root ports
64 with a total of 5 lanes. Some boards require this for Ethernet
65 support to work (e.g. beaver, jetson-tk1).
