[PATCH v4 0/7] AML Housekeeping

[Bernhard Beschow]

This series factors out AcpiCpuAmlIfClass::madt_cpu from AcpiDeviceIfClass.
By letting the (x86) CPUs implement the new interface, AML generation is
delegated to the CPUs, freeing the ACPI controllers from worrying about x86 CPU
specifics. The delegation to the CPUs is especially interesting for the PIIX4 PM
since it is also used in MIPS only contexts where no ACPI bios is available.

Furthermore, the series introduces qbus_build_aml() which replaces
isa_build_aml() and resolves some open coding.

v4:
- Squash qbus_build_aml() patches into one (Igor)
- Don't use a bare function pointer for AcpiDeviceIfClass::madt_cpu (Igor)

Testing done:
* `make check`
* `qemu-system-x86_64 -M pc -m 2G -cdrom manjaro-kde-21.2.6-220416-linux515.iso`
* `qemu-system-x86_64 -M q35 -m 2G -cdrom \
   manjaro-kde-21.2.6-220416-linux515.iso`

v3:
- Clean up includes in AcpiDeviceIfClass::madt_cpu sub series last (Markus)
- Restructure qbus_build_aml() sub series (Phil, me)

v2:
- Don't inline qbus_build_aml() (Phil)
- Add 'hw/acpi/piix4: No need to #include "hw/southbridge/piix.h"'

Bernhard Beschow (7):
  hw/i386/acpi-build: Remove unused attributes
  hw/isa/isa-bus: Turn isa_build_aml() into qbus_build_aml()
  hw/acpi/piix4: No need to #include "hw/southbridge/piix.h"
  hw/acpi/acpi_dev_interface: Remove unused parameter from
    AcpiDeviceIfClass::madt_cpu
  hw/acpi/acpi_dev_interface: Factor out TYPE_ACPI_CPU_AML_IF
  hw/acpi/acpi_dev_interface: Remove now unused #include "hw/boards.h"
  hw/i386/pc: Unexport pc_madt_cpu_entry()
