[PATCH v2 0/6] QOM'ify PIIX southbridge creation


From: Bernhard Beschow
Subject: [PATCH v2 0/6] QOM'ify PIIX southbridge creation
Date: Sun, 22 May 2022 23:24:25 +0200

v2:
* Preserve `DeviceState *` as return value of piix4_create() (Mark)
* Aggregate all type name movements into first commit (Mark)
* Have piix4 southbridge rather than malta board instantiate piix4 pm (me)

Testing done:

1)
`make check-avocado` for --target-list=x86_64-softmmu,mips-softmmu
Result: All pass.

2)
Modify pci_piix3_realize() to start with
    error_setg(errp, "This is a test");
Then start `qemu-system-x86_64 -M pc -m 1G -accel kvm -cpu host -cdrom 
archlinux-2022.05.01-x86_64.iso`.
Result: qemu-system-x86_64 aborts with: "This is a test"


v1:
The piix3 and piix4 southbridge devices still rely on create() functions which
are deprecated. This series resolves these functions piece by piece to
modernize the code.

Both devices are modified in lockstep where possible to provide more context.

Testing done:
* `qemu-system-x86_64 -M pc -m 2G -cdrom archlinux-2022.05.01-x86_64.iso`
* `qemu-system-mipsel -M malta -kernel vmlinux-3.2.0-4-4kc-malta -hda 
debian_wheezy_mipsel_standard.qcow2 -append "root=/dev/sda1 console=tty0"`

In both cases the system booted successfully and it was possible to shut down
the system using the `poweroff` command.
