When the IOMMU is implemented as a PCI device, its BDF is created locally in virt.c. However, the same BDF is also required in virt-acpi-build.c to support ACPI. Therefore, make this information part of the global RISCVVirtState structure so that it can be accessed outside of virt.c as well. Signed-off-by: Sunil V L <[email protected]> ---
