config PCI_ENDPOINT
	bool "PCI Endpoint Support"
	depends on HAS_DMA
	help
	   Enable this configuration option to support configurable PCI
	   endpoint. This should be enabled if the platform has a PCI
	   controller that can operate in endpoint mode.

	   Enabling this option will build the endpoint library, which
	   includes endpoint controller library and endpoint function
	   library.

	   If in doubt, say "N" to disable Endpoint support.

config PCI_ENDPOINT_CONFIGFS
	bool "PCI Endpoint Configfs Support"
	depends on PCI_ENDPOINT
	select CONFIGFS_FS
	help
	   This will enable the configfs entry that can be used to
	   configure the endpoint function and used to bind the
	   function with a endpoint controller.

PCI: Add SPDX GPL-2.0 when no license was specified b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") added SPDX GPL-2.0 to several PCI files that previously contained no license information. Add SPDX GPL-2.0 to all other PCI files that did not contain any license information and hence were under the default GPL version 2 license of the kernel.

PCI: endpoint: Add EP core layer to enable EP controller and EP functions Introduce a new EP core layer in order to support endpoint functions in linux kernel. This comprises the EPC library (Endpoint Controller Library) and EPF library (Endpoint Function Library).
