Not all interrupt controllers have a working implementation of
message-signalled interrupts; in some cases, the guest may expect
MSI to work but it won't due to the buggy or lacking emulation.
In QEMU this is represented by the "msi_nonbroken" variable. This
patch adds a new configuration symbol enabled whenever the binary
contains an interrupt controller that will set "msi_nonbroken". We
can then use it to remove devices that cannot be possibly added
to the machine, because they require MSI.

Instead of including the same list of devices for each target,
set CONFIG_PCI to true, and make the devices default to present
whenever PCI is available. However, s390x does not want all the
PCI devices, so there is a separate symbol to enable them.
Done mostly with the following script:
while read i; do
i=${i%=y}; i=${i#CONFIG_}
sed -i -e'/^config '$i'$/!b' -en \
-e'a\' -e' default y if PCI_DEVICES\' -e' depends on PCI' \
`grep -lw $i hw/*/Kconfig`
done < default-configs/pci.mak
followed by replacing a few "depends on" clauses with "select"
whenever the symbol is not really related to PCI.

This patch adds an optional function pointer, 'elf_note_fn', to
load_elf() which causes load_elf() to additionally parse any
ELF program headers of type PT_NOTE and check to see if the ELF
Note is of the type specified by the 'translate_opaque' arg.
If a matching ELF Note is found then the specfied function pointer
is called to process the ELF note.
Passing a NULL function pointer results in ELF Notes being skipped.
The first consumer of this functionality is the PVHboot support
which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while
loading the uncompressed kernel binary in order to discover the
boot entry address for the x86/HVM direct boot ABI.

The 'q35' machine type implements an Intel Series 3 chipset,
of which there are several variants:
https://www.intel.com/Assets/PDF/datasheet/316966.pdf
The key difference between the 82P35 MCH ('p35', PCI device ID 0x29c0)
and 82Q35 GMCH ('q35', PCI device ID 0x29b0) variants is that the latter
has an integrated graphics adapter. QEMU does not implement integrated
graphics, so uses the PCI ID for the 82P35 chipset, despite calling the
machine type 'q35'. Thus we rename the PCI device ID constant to reflect
reality, to avoid confusing future developers. The new name more closely
matches what pci.ids reports it to be:
$ grep P35 /usr/share/hwdata/pci.ids | grep 29
29c0 82G33/G31/P35/P31 Express DRAM Controller
29c1 82G33/G31/P35/P31 Express PCI Express Root Port
29c4 82G33/G31/P35/P31 Express MEI Controller
29c5 82G33/G31/P35/P31 Express MEI Controller
29c6 82G33/G31/P35/P31 Express PT IDER Controller
29c7 82G33/G31/P35/P31 Express Serial KT Controller
$ grep Q35 /usr/share/hwdata/pci.ids | grep 29
29b0 82Q35 Express DRAM Controller
29b1 82Q35 Express PCI Express Root Port
29b2 82Q35 Express Integrated Graphics Controller
29b3 82Q35 Express Integrated Graphics Controller
29b4 82Q35 Express MEI Controller
29b5 82Q35 Express MEI Controller
29b6 82Q35 Express PT IDER Controller
29b7 82Q35 Express Serial KT Controller
Arguably the QEMU machine type should be named 'p35'. At this point in
time, however, it is not worth the churn for management applications &
documentation to worry about renaming it.

In commit 9fa99d2519 ("hw/pci-host: Fix x86 Host Bridges 64bit PCI
hole", 2017-11-16), we meant to expose such a 64-bit PCI MMIO aperture in
the ACPI DSDT that would be at least as large as the new "pci-hole64-size"
property (2GB on i440fx, 32GB on q35). The goal was to offer "enough"
64-bit MMIO aperture to the guest OS for hotplug purposes.
In that commit, we added or modified five functions:
- pc_pci_hole64_start(): shared between i440fx and q35. Provides a default
64-bit base, which starts beyond the cold-plugged 64-bit RAM, and skips
the DIMM hotplug area too (if any).
- i440fx_pcihost_get_pci_hole64_start(), q35_host_get_pci_hole64_start():
board-specific 64-bit base property getters called abstractly by the
ACPI generator. Both of these fall back to pc_pci_hole64_start() if the
firmware didn't program any 64-bit hole (i.e. if the firmware didn't
assign a 64-bit GPA to any MMIO BAR on any device). Otherwise, they
honor the firmware's BAR assignments (i.e., they treat the lowest 64-bit
GPA programmed by the firmware as the base address for the aperture).
- i440fx_pcihost_get_pci_hole64_end(), q35_host_get_pci_hole64_end():
these intended to extend the aperture to our size recommendation,
calculated relative to the base of the aperture.
Despite the original intent, i440fx_pcihost_get_pci_hole64_end() and
q35_host_get_pci_hole64_end() currently only extend the aperture relative
to the default base (pc_pci_hole64_start()), ignoring any programming done
by the firmware. This means that our size recommendation may not be met.
Fix it by honoring the firmware's address assignments.
The strange extension sizes were spotted by Alex, in the log of a guest
kernel running on top of OVMF (which prefers to assign 64-bit GPAs to
64-bit BARs).
This change only affects DSDT generation, therefore no new compat property
is being introduced.

(5-3) = 6 GB. Adding the 2GB extension to that yields 8GB, which is below
the firmware-programmed base of 32GB, before the patch. Therefore, before
the patch, the extension is ineffective. After the patch, we add the 2GB

According to the PReP specification section 6.1.6 "System Interrupt
Assignments", all PCI interrupts are routed via IRQ 15.
Instead of mapping each PCI IRQ separately, we introduce an OR gate within the
raven PCI host bridge and then wire the single output of the OR gate to the
interrupt controller.
Note that whilst the (now deprecated) PReP machine still exists we still need
to preserve the old IRQ routing. This is done by adding a new "is-legacy-prep"
property to the raven PCI host bridge which is set to true for the PReP
machine.

Currently we use memory_region_init_rom_nomigrate() to create
the "io" memory region to pass to pci_register_root_bus().
This is a dummy region, because this PCI controller doesn't
support accesses to PCI IO space.
There is no reason for the dummy region to be a RAM region;
it is only used as a place where PCI BARs can be mapped,
and if you could get a PCI card to do a bus master access
to the IO space it should not get acts-like-RAM behaviour.
Use a simple container memory region instead. (We do have
one PCI card model which can do bus master accesses to IO
space -- the LSI53C895A SCSI adaptor.)
This avoids the oddity of having a memory region which is
RAM but where the RAM is not migrated.
Note that the size of the region we use here has no
effect on behaviour.

>From observation of various OS sources it can be seen that the token register
introduced in 4e46dcdbd3 "PPC: Newworld: Add uninorth token register" is not
required, since the only register currently implemented is the uninorth hardware
version which is read-only.
Remove the token register implementation and instead return the uninorth
version corresponding to the hardware.

During smram region initialization some addresses are hardcoded,
replace them with macro to be more clear to readers.

Commit 4e46dcdbd3 "PPC: Newworld: Add uninorth token register" added a TODO

these registers to a new uninorth device, removing the old hacks from

Somewhere in the history of time, the initialisation of the PCI buses for the
AGP and PCI host bridges got mixed up in that the PCI host bridge was
creating an instance of the AGP PCI bus, and the AGP PCI bus was missing.
Swap the PCI host bridge over to use the correct PCI bus (including setting
the kMacRISCPCIAddressSelect register used by MacOS X) and add the missing
reference to the AGP PCI bus.

Since the IO address space is fixed to use the standard system IO address
space then we can also use the opportunity to remove the address_space_io
parameter from pci_pmac_init() and pci_pmac_u3_init().
Note we also move the default mac99 PCI bus to the end of the initialisation
list so that it becomes the default destination for any devices specified
via -device without an explicit PCI bus provided.
