From 34aff14580d1b02971adfd63be994f9c045919aa Mon Sep 17 00:00:00 2001 From: Jason Andryuk Date: Wed, 14 Oct 2020 13:53:40 -0400 Subject: xen: Remove Xen PVH/PVHVM dependency on PCI A Xen PVH domain doesn't have a PCI bus or devices, so it doesn't need PCI support built in. Currently, XEN_PVH depends on XEN_PVHVM which depends on PCI. Introduce XEN_PVHVM_GUEST as a toplevel item and change XEN_PVHVM to a hidden variable. This allows XEN_PVH to depend on XEN_PVHVM without PCI while XEN_PVHVM_GUEST depends on PCI. In drivers/xen, compile platform-pci depending on XEN_PVHVM_GUEST since that pulls in the PCI dependency for linking.
