12 Enable this configuration option to support configurable PCI
13 endpoint. This should be enabled if the platform has a PCI
14 controller that can operate in endpoint mode.

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

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

35 This enables the EP's MSI interrupt controller to function as a
36 doorbell. The RC can trigger doorbell in EP by writing data to a
37 dedicated BAR, which the EP maps to the controller's message address.
