The "OvmfPkg/Library/PciHostBridgeLib/PciHostBridgeLib.inf" instance is used by the following platforms in edk2: OvmfPkg/AmdSev/AmdSevX64.dsc OvmfPkg/OvmfPkgIa32.dsc OvmfPkg/OvmfPkgIa32X64.dsc OvmfPkg/OvmfPkgX64.dsc All these platforms statically inherit PcdPciDisableBusEnumeration=FALSE from "MdeModulePkg.dec". Remove the the PCD and everything that depends on it from the PciHostBridgeLib instance. Namely, remove the logic that determines the root bridge apertures by (a) scanning the entire bus, device and function number space, and (b) parsing the BAR values that were pre-set by the Bhyve or Xen machinery. "XenSupport.c" used to be listed explicitly in "Maintainers.txt", remove it from that spot too.
