	We eventually need to drop the compatibility functions for driver model. As a first step, create a configuration option to enable them and hide them when the option is disabled. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

| 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 DM_PCI_COMPAT
 | |
| 	bool "Enable compatible functions for PCI"
 | |
| 	depends on DM_PCI
 | |
| 	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.
 | |

| 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.

| config PCI_TEGRA
 | |
| 	bool "Tegra PCI support"
 | |
| 	depends on TEGRA
 | |
| 	help
 | |
| 	  Enable support for the PCIe controller found on some generations of
 | |
| 	  Tegra. Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has
 | |
| 	  3 root ports with a total of 6 lanes and Tegra124 has 2 root ports
 | |
| 	  with a total of 5 lanes. Some boards require this for Ethernet
 | |
| 	  support to work (e.g. beaver, jetson-tk1).
