[PATCH 00/12] hw: Strengthen SysBus & QBus API

[Philippe Mathieu-Daudé]

Hi,

This series ensure:

- qbus_new() and sysbus_init_mmio() are called *before*
  a device is realized,
- sysbus_mmio_map() is called *after* it is realized.

First we fix some abuse, then we enforce in qdev/sysbus
core code.

Philippe Mathieu-Daudé (12):
  hw/i386/amd_iommu: Do not use SysBus API to map local MMIO region
  hw/i386/intel_iommu: Do not use SysBus API to map local MMIO region
  hw/misc/allwinner-dramc: Move sysbus_mmio_map call from init ->
    realize
  hw/misc/allwinner-dramc: Do not use SysBus API to map local MMIO
    region
  hw/pci-host/bonito: Do not use SysBus API to map local MMIO region
  hw/acpi: Realize ACPI_GED sysbus device before accessing it
  hw/arm/virt: Realize ARM_GICV2M sysbus device before accessing it
  hw/isa: Realize ISA BUS sysbus device before accessing it
  hw/s390x/css-bridge: Realize sysbus device before accessing it
  hw/qdev: Ensure parent device is not realized before adding bus
  hw/sysbus: Ensure device is not realized before adding MMIO region
  hw/sysbus: Ensure device is realized before mapping it
