An ICH9 southbridge contains several PCI devices, some of them with
multiple functions. We model each function as a separate qdev. Two
of them need some special wiring set up in pc_q35_init() to work: the
LPC controller at 00:1f.0, and the SMBus controller at 00:1f.3.

Many PCI host bridges consist of a sysbus device and a PCI device.
You need both for the thing to work. Arguably, these bridges should
be modelled as a single, composite devices instead of pairs of
seemingly independent devices you can only use together, but we're not
there, yet.
Since the sysbus part can't be instantiated with device_add, yet,
permitting it with the PCI part is useless. We shouldn't offer
useless options to the user, so let's set
cannot_instantiate_with_device_add_yet for them.
It's already set for Bonito, Grackle, i440FX and Raven. Document why.
Set it for the others: dec-21154, e500-host-bridge, gt64120_pci, mch,
pbm-pci, ppc4xx-host-bridge, sh_pci_host, u3-agp, uni-north-agp,
uni-north-internal-pci, uni-north-pci, and versatile_pci_host.

device_add plugs devices into suitable bus. For "real" buses, that
actually connects the device. For sysbus, the connections need to be
made separately, and device_add can't do that. The device would be
left unconnected, and could not possibly work.
Quite a few, but not all sysbus devices already set
cannot_instantiate_with_device_add_yet in their class init function.
Set it in their abstract base's class init function
sysbus_device_class_init(), and remove the now redundant assignments
from device class init functions.

In an ideal world, machines can be built by wiring devices together
with configuration, not code. Unfortunately, that's not the world we
live in right now. We still have quite a few devices that need to be
wired up by code. If you try to device_add such a device, it'll fail
in sometimes mysterious ways. If you're lucky, you get an
unmysterious immediate crash.
To protect users from such badness, DeviceClass member no_user used to
make device models unavailable with -device / device_add, but that
regressed in commit 18b6dad. The device model is still omitted from
help, but is available anyway.
Attempts to fix the regression have been rejected with the argument
that the purpose of no_user isn't clear, and it's prone to misuse.
This commit clarifies no_user's purpose. Anthony suggested to rename
it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which
I shorten somewhat to keep checkpatch happy. While there, make it
bool.
Every use of cannot_instantiate_with_device_add_yet gets a FIXME
comment asking for rationale. The next few commits will clean them
all up, either by providing a rationale, or by getting rid of the use.
With that done, the regression fix is hopefully acceptable.

The SPAPR specification says that the RMA starts at the LPAR's logical
address 0 and is the first logical memory block reported in
the LPAR’s device tree.
So SLOF only maps the first block and that block needs to span
the full RMA.
This makes sure that the RMA area is where SLOF expects it.

We use the rom infrastructure to write firmware and/or initial kernel
blobs into guest address space. So we're basically emulating the cache
off phase on very early system bootup.
That phase is usually responsible for clearing the instruction cache for
anything it writes into cachable memory, to ensure that after reboot we
don't happen to execute stale bits from the instruction cache.
So we need to invalidate the icache every time we write a rom into guest
address space. We do not need to do this for every DMA since the guest
expects it has to flush the icache manually in that case.
This fixes random reboot issues on e5500 (booke ppc) for me.

There's no good reason to call our bus "pci" rather than let the default
bus name take over ("pci.0").
The big downside to calling it different from anyone else is that tools
that pass -device get confused. They are looking for a bus "pci.0" rather
than "pci".
To make life easier for everyone, let's just drop the name override.

For AArch64 we will obviously require a different set of
primary and secondary boot loader code fragments. However currently
we hardcode the offsets into the loader code where we must write
the entrypoint and other data into arm_load_kernel(). This makes it
hard to substitute a different loader fragment, so switch to a more
flexible scheme where instead of a raw array of instructions we use
an array of (instruction, fixup-type) pairs that indicate which
words need special action or data written into them.

Fix NOR flash manufacturer and device ID reading. This now
properly takes into account device widths and device max widths
as required. The reading of these IDs uses the same max_width
dependent addressing as CFI queries.
The old code remains for chips that don't specify a device width,
as the new code relies on a device width being set in order to
properly operate. The existing code seems very broken.
Only ident0 and ident1 are used in the new code, as other fields
relate to the lock state of blocks in flash.
The VExpress flash configuration has been updated to match
the new code, as the existing definition was 'wrong' in order
to return the expected results with the broken device ID code.

This change fixes the CFI query responses to handle NOR device
widths that are different from the bank width. Support is also
added for multi-width devices in a x8 configuration. This is
typically x8/x16 devices, but the CFI specification mentions
x8/x32 devices so those should be supported as well if they
exist.
The query response data is now replicated per-device in the bank,
and is adjusted for x16 or x32 parts configured in x8 mode.
The existing code is left in place for boards that have not
been updated to specify an explicit device_width. The VExpress
board has been updated in an earlier patch in this series so
this is the only board currently affected.

For handling CFI and device ID reads, we need to not only know the
width that a NOR flash device is configured for, but also its maximum
width. The maximum width addressing mode is used for multi-width
parts no matter which width they are configured for. The most common
case is x16 parts that also support x8 mode. When configured for x8
operation these devices respond to CFI and device ID requests differently
than native x8 NOR parts.

The width of the devices that make up the flash interface
is required to mask certain commands, in particular the
write length for buffered writes. This length will be presented
to each device on the interface by the program writing the flash,
and the flash emulation code needs to be able to determine
the length of the write as recieved by each flash device.
The device-width defaults to the bank width which should
maintain existing behavior for platforms that don't need
this change.
This change is required to support buffered writes on the
vexpress platform that has a 32 bit flash interface with 2
16 bit devices on it.

There are also some changes mostly useful for downstreams.

Owning to some different hardware design, piix and q35 need
different compat. So making them diverge.
On q35, IRQ2/8 can be reserved for hpet timer 0/1. And pin 16~23
can be assigned to hpet as guest chooses. So we introduce intcap
property to do that.
Consider the compat and piix/q35, we finally have the following
value for intcap: For piix, hpet's intcap is hard coded as IRQ2.
For pc-q35-1.7 and earlier, we use IRQ2 for compat reason. Otherwise
IRQ2, IRQ8, and IRQ16~23 are allowed.

According to hpet spec, hpet irq is high active. But according to
ICH spec, there is inversion before the input of ioapic. So the OS
will expect low active on this IRQ line. (On bare metal, if OS driver
claims high active on this line, spurious irq is generated)
We fold the emulation of this inversion inside the hpet logic.

qemu uses "pci" as name for pci bridges in the firmware device path.
seabios expects "pci-bridge". Result is that bootorder is broken for
devices behind pci bridges.
Some googling suggests that "pci-bridge" is the correct one. At least
PPC-based Apple machines are using this. See question "How do I boot
from a device attached to a PCI card" here:
http://www.netbsd.org/ports/macppc/faq.html
So lets change qemu to use "pci-bridge" too.

Currently this just floods indicating that can_receive has been called
by the net framework. Instead, save the result of the most recent
can_receive callback as state and only print a message if the result
changes (indicating some sort of actual state change in GEM). Make said
debug message more meaningful as well.
