[PATCH v2 0/6] VIA and general PCI IDE cleanup

From: Bernhard Beschow
Subject: [PATCH v2 0/6] VIA and general PCI IDE cleanup
Date: Tue, 23 May 2023 21:49:24 +0200

This series is split off from a more general PCI IDE refactoring aiming for a
common implementation of the PCI IDE controller specification for all
TYPE_PCI_IDE models [1].

The first three patches resolve a circular dependency between the VIA IDE
controller and its south bridge. The next two patches resolves redundant code
accross all TYPE_PCI_IDE models. The last patch modernizes VM state setup in

Testing done:
* `make check`
* `make check-avocado`
* `qemu-system-ppc -machine pegasos2 -rtc base=localtime -device \
   ati-vga,guest_hwcursor=true,romfile="" -cdrom morphos-3.17.iso \
   -bios pegasos2.rom`
   The machine booted successfully and a startup sound was hearable
* `qemu-system-ppc -machine sam460ex -rtc base=localtime -drive \
   if=none,id=cd,file=morphos-3.17.iso,format=raw -device \
   The machine booted successfully into graphical desktop environment

* Add missing Signed-off-by tag to last commit (Zoltan)

Changes since [1]:
* Turn legacy IRQs into named GPIOs (Mark)
* Don't make VIA IDE legacy IRQs routable; just wire up in host device (Zoltan)
* Rename extracted bmdma_clear_status() (Zoltan)
   ... to bmdma_status_writeb() (Mark)


Bernhard Beschow (6):
  hw/ide/pci: Expose legacy interrupts as named GPIOs
  hw/ide/via: Wire up IDE legacy interrupts in host device
  hw/isa/vt82c686: Remove via_isa_set_irq()
  hw/ide: Extract IDEBus assignment into bmdma_init()
  hw/ide: Extract bmdma_status_writeb()
  hw/ide/piix: Move registration of VMStateDescription to DeviceClass
