This series implements relocation of the SuperI/O functions of the VIA south
bridges which resolves some FIXME's. It is part of my via-apollo-pro-133t
branch [1] which is an extension of bringing the VIA south bridges to the PC
machine [2]. This branch is able to run some real-world X86 BIOSes in the hope
that it allows us to form a better understanding of the real vt82c686b devices.
Implementing relocation and toggling of the SuperI/O functions is one step to
make these BIOSes run without error messages, so here we go.
The series is structured as follows: Patches 1-3 prepare the TYPE_ISA_FDC,
TYPE_ISA_PARALLEL and TYPE_ISA_SERIAL to relocate and toggle (enable/disable)
themselves without breaking encapsulation of their respective device states.
This is achieved by moving the MemoryRegions and PortioLists from the device
states into the encapsulating ISA devices since they will be relocated and
toggled.
Inspired by the memory API patches 4-6 add two convenience functions to the
portio_list API to toggle and relocate portio lists. Patch 5 is a preparation
for that which removes some redundancies which otherwise had to be dealt with
during relocation.
Patches 7-9 implement toggling and relocation for types TYPE_ISA_FDC,
TYPE_ISA_PARALLEL and TYPE_ISA_SERIAL. Patch 10 prepares the pegasos2 machine
which would end up with all SuperI/O functions disabled if no -bios argument is
given. Patch 11 finally implements the main feature which now relies on
firmware to configure the SuperI/O functions accordingly (except for pegasos2).
v4:
* Drop incomplete SuperI/O vmstate handling (Zoltan)
v3:
* Rework various commit messages (Zoltan)
* Drop patch "hw/char/serial: Free struct SerialState from MemoryRegion"
(Zoltan)
* Generalize wording in migration.rst to include portio_list API (Zoltan)
v2:
* Improve commit messages (Zoltan)
* Split pegasos2 from vt82c686 patch (Zoltan)
* Avoid poking into device internals (Zoltan)
Testing done:
* `make check`
* `make check-avocado`
* Run MorphOS on pegasos2 with and without pegasos2.rom
* Run Linux on amigaone
* Run real-world BIOSes on via-apollo-pro-133t branch
* Start rescue-yl on fuloong2e

(Paolo?). The portio_list_set_enabled() API looks interesting, and could be considered for use by my PCI IDE mode-switching changes too. Apologies I don't have a huge amount of time for review right now, but I wanted to feed back that generally these patches look good, and if people are happy with the portio list changes then this series should be considered for merge.

Thanks :) Agreed. I *think* the portio_lists are ISA-specific as far as QEMU is concerned, but a quick nod from an x86 maintainer would be a great help :) >> The portio_list_set_enabled() API looks interesting, and could be considered for use by my PCI IDE mode-switching changes too. >> >> Apologies I don't have a huge amount of time for review right now, but I wanted to feed back that generally these patches look good, and if people are happy with the portio list changes then this series should be considered for merge. > > Never mind, it's still nice getting some confirmation from your side!

I think of patches 1 - 3 more as cleanups where an attribute unused in the core is moved one level up to where it is needed.
