This is now done sloppily, via get_system_memory(). Eventually callers

There's no need to bswap once we correctly set the mmio to be little endian.

The only reason we have bswap versions of the pci host code is that
most pci host devices are little endian. The ppc e500 is the only
odd one here, being big endian.
So let's directly pass the endianness down to the mmio layer and not
worry about it on the pci host layer.

As an alternative to the 3 individual handlers, there is also a simplified
io mem hook function. To be consistent, let's add an endianness parameter
there too.

Don't overwrite pci header type.
Otherwise, multi function bit which pci_init_header_type() sets
appropriately is lost.
Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zero
which is already zero cleared.
how to test:
run qemu and issue info pci to see whether a device in question is
normal device, not pci-to-pci bridge.
This is handy because guest os isn't required.

The interrupt code as is didn't really work for me. I couldn't even convince
Linux to take interrupt 9 in an interrupt-map.
So let's do this right. Let's map all PCI interrupts to 0x1b - 0x1e. That way
we're at least a small step closer to what real hardware does.
I also took the interrupt pin to line conversion from OpenBIOS, which at least
assures us we're compatible with our firmware :-).
A dump of the PCI interrupt-map from a U2 (iBook):

The "Mac99" type so far defines a "U2" based configuration. Unfortunately,
there have never been any U2 based PPC64 machines. That's what the U3 was
developed for.
So let's split the Mac99 machine in a PPC64 and a PPC32 machine. The PPC32
machine stays "Mac99", while the PPC64 one becomes "Mac99_U3". All peripherals
stay the same.

The Uninorth PCI bridge requires different layouts in its PCI config space
accessors.
This patch introduces a conversion function that makes it compatible with
the way Linux accesses it.
I also kept an OpenBIOS compatibility hack in. I think it'd be better to
take small steps here and do the config space access rework in OpenBIOS
later on. When that's done we can remove that hack.

Before 2e29bd04786003561303dcad940b38afe790fb9b, Uni-North host and AGP
bridge were using the same devfn, 11 << 3. The net effect was that only
AGP bridge was visible. This was changed in the commit to 13 << 3 for AGP.
Some of the later crashes happened due to NULL pointer dereferences generated
by 07b7d05377a5e2b242ef0cce3d461d3284700fc0 and insufficient return value
checks.
Disable host device and revert AGP to 11 << 3.

split static functions in pci_host.h into pci_host.c and
pci_host_template.h.
Later a structures declared in pci_host.h, PCIHostState, will be used.
However pci_host.h doesn't allow to include itself easily. This patches
addresses it.
pci_host.h includes functions which are instantiated in .c by including
pci_host.h with typedefing pci_addr_t.
pci_addr_t is per pci host bridge and is typedef'ed to uint32_t for ioio
or target_phys_addr_t for mmio in .c file.
That prevents from including pci_host.h to use PCIHostState because of
requiring type, pci_addr_t.
Its purpose to include is to instantiate io function for mmio or ioio
depending on which pci host bridge requires ioio or mmio.
To avoid including code, we always instantiate both version.

Like qdev_init(), but terminate program via hw_error() instead of
returning an error value.
Use it instead of qdev_init() where terminating the program on failure
is okay, either because it's during machine construction, or because
we know that failure can't happen.
Because relying in the latter is somewhat unclean, and the former is
not always obvious, it would be nice to go back to qdev_init() in the
not-so-obvious cases, only with proper error handling. I'm leaving
that for another day, because it involves making sure that error
values are properly checked by all callers.

The naming convention is goofy and it causes a massive merge problem. Something

Sorry folks, but it has to be. One more of these invasive qdev patches.
We have a serious design bug in the qdev interface: device init
callbacks can't signal failure because the init() callback has no
return value. This patch fixes it.
We have already one case in-tree where this is needed:
Try -device virtio-blk-pci (without drive= specified) and watch qemu
segfault. This patch fixes it.
With usb+scsi being converted to qdev we'll get more devices where the
init callback can fail for various reasons.

Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.
Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.
