	 Enables support for the PCIe controller in the DRA7xx SoC. There
	 are two instances of PCIe controller in DRA7xx. This controller can
	 work either as EP or RC. In order to enable host-specific features
	 PCI_DRA7XX_HOST must be selected and in order to enable device-
	 specific features PCI_DRA7XX_EP must be selected. This uses
	 the Designware core.

	 Enables support for the PCIe controller in the DRA7xx SoC to work in
	 host mode.

config PCI_DRA7XX_EP
	bool "PCI DRA7xx Endpoint Mode"
	depends on PCI_ENDPOINT
	select PCIE_DW_EP

	---help---
	 This selects the DesignWare PCIe controller support. Select this if
	 you have a PCIe controller on Platform bus.

	 If you have a controller with this interface, say Y or M here.

	 If unsure, say N.

	help
	  Say Y here if you want to enable PCI controller support on Keystone
	  SoCs. The PCI controller on Keystone is based on Designware hardware
	  and therefore the driver re-uses the Designware core functions to
	  implement the driver.
