It's possible to create non-working configurations by attaching a device to a derivative of PCIe slot (pcie-root-port, ioh3420, etc) and specifying a slot number other that zero, e.g.:-device pcie-root-port,id=s0,... \ -device virtio-blk-pci,bus=s0,addr=4,... Make QEMU reject such configurations and only allow addr=0 on the secondary bus of a PCIe slot. To verify this new behavior, add two basic qtests for the PCIe bridges that may be affected by change: pcie-root-port and x3130. For the former, two testcases are included, one positive for slot #0 and one negative for (arbitrary) slot #4; for the latter, only a positive testcase for slot #4 is included.
