[PATCH v6 13/15] hw/pci: Determine if rombar is explicitly enabled |
Date: |

vfio determines if rombar is explicitly enabled by inspecting QDict.
Inspecting QDict is not nice because QDict is untyped and depends on the
details on the external interface. Add an infrastructure to determine if
rombar is explicitly enabled to hw/pci.
