TYPE_VIA_PM calls apm_init() in via_pm_realize(), so
requires APM to be selected.

In VIA super south bridge the io ranges of superio components
(parallel and serial ports and FDC) can be controlled by superio
config registers to set their base address and enable/disable them.
This is not easy to implement in QEMU because ISA emulation is only
designed to set io base address once on creating the device and io
ranges are registered at creation and cannot easily be disabled or
moved later.
In this patch we hack around that but only for serial ports because
those have a single io range at port base that's relatively easy to
handle and it's what guests actually use and set address different
than the default.
We do not attempt to handle controlling the parallel and FDC regions
because those have multiple io ranges so handling them would be messy
and guests either don't change their deafult or don't care. We could
even get away with disabling and not emulating them, but since they
are already there, this patch leaves them mapped at their default
address just in case this could be useful for a guest in the future.

Add emulation of VT8231 south bridge ISA part based on the similar
VT82C686B but implemented in a separate subclass that holds the
differences while reusing parts that can be shared.

The VT8231 south bridge is very similar to VT82C686B but there are
some differences in register addresses and functionality, e.g. the
VT8231 only has one serial port. This commit adds VT8231_SUPERIO
subclass based on the abstract VIA_SUPERIO class to emulate the
superio part of VT8231.

To allow reusing ISA bridge emulation for vt8231_isa move the device
state of vt82c686b_isa emulation in an abstract via_isa class. This
change breaks migration back compatibility but this is not an issue
for Fuloong2E machine which is not versioned or migration supported.

This should be OK if this other series is accepted:
"hw/usb: Extract Extract VT82C686 UHCI PCI function into new unit"
https://lists.gnu.org/archive/html/qemu-devel/2021-03/msg03083.html
I'll come back to this patch after the former series is reviewed.

How is this patch related to that series? This one changes the isa bridge
part and that makes the usb part compiled only if configured. These seem
unrelated and independent to me.

Collect superio functionality and its controlling config registers
handling in an abstract VIA_SUPERIO class that is a subclass of
ISA_SUPERIO and put vt82c686b specific parts in a subclass of this
abstract class.

Unfortunately this doesn't work because errp can be NULL...
This is described in "qapi/error.h". You have to use a local_err.

The Marvell Discovery II aka. MV64361 is a PowerPC system controller
chip that is used on the pegasos2 PPC board. This adds emulation of it
that models the device enough to boot guests on this board. The
mv643xx.h header with register definitions is taken from Linux 4.15.10
only fixing white space errors, removing not needed parts and changing
formatting for QEMU coding style.

To: qemu-devel, qemu-ppc; +Cc: Peter Maydell, Paolo Bonzini, f4bug, David Gibson
Add new machine called pegasos2 emulating the Genesi/bPlan Pegasos II,
a PowerPC board based on the Marvell MV64361 system controller and the
VIA VT8231 integrated south bridge/superio chips. It can run Linux,
AmigaOS and a wide range of MorphOS versions. Currently a firmware ROM
image is needed to boot and only MorphOS has a video driver to produce
graphics output. Linux could work too but distros that supported this
machine don't include usual video drivers so those only run with
serial console for now.
