The ARM_CPU_IRQ/FIQ definitions are used to index the GPIO
IRQ created calling qdev_init_gpio_in() in ARMCPU instance_init()
handler. To allow non-ARM code to raise interrupt on ARM cores,
move they to 'target/arm/cpu-qom.h' which is non-ARM specific and
can be included by any hw/ file.

This query copies the kernel command line into the message buffer. It
was previously stubbed out to return empty, this commit makes it reflect
the arguments specified with `-append`.
I observed the following peculiarities on my Pi 3B+:
- If the buffer is shorter than the string, the response header gives
the full length, but no data is actually copied.
- No NUL terminator is added: even if the buffer is long enough to fit
one, the buffer's original contents are preserved past the string's
end.
- The VC firmware adds the following extra parameters beside the
user-supplied ones (via /boot/cmdline.txt): `video`, `vc_mem.mem_base`
and `vc_mem.mem_size`. This is currently not implemented in qemu.

Not exactly elegant, I'm afraid.
The "when != lbl:" is necessary to avoid transforming
if (fun(args, &err)) {
goto out
}
...
out:
error_propagate(errp, err);
even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().
Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly. I don't know what exactly "when strict" does, only that
it helps here.
The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err". For
an example where it's too narrow, see vfio_intx_enable().

The only way object_property_add() can fail is when a property with
the same name already exists. Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.
Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent. Parentage is
also under program control, so this is a programming error, too.
We have a bit over 500 callers. Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.
The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.
Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call. ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.
When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.
Drop parameter @errp and assert the preconditions instead.
There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification". Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

The qdev_set_parent_bus() from instance_init adds a link to the child devices
which is not valid anymore after the bcm2837 instance has been destroyed.
Unfortunately, the child devices do not get destroyed / unlinked correctly
because both object_initialize() and object_property_add_child() increase
the reference count of the child objects by one, but only one reference
is dropped when the parent gets removed. So let's use the new functions
object_initialize_child() and sysbus_init_child_obj() instead to create
the objects, which will take care of creating the child objects with the
correct reference count of one.

These devices are currently causing some problems when a user is trying
to hot-plug or introspect them during runtime. Since these devices can
not be instantiated by the user at all (they need to be wired up in code
instead), we should mark them with user_creatable = false anyway, then we
avoid at least the crashes with the hot-plugging. The introspection problem
will be handled by a separate patch.

Now we have separate types for BCM2386 and BCM2387, we might as well
just hard-code the CPU type they use rather than having it passed
through as an object property. This then lets us put the initialization
of the CPU object in init rather than realize.
Note that this change means that it's no longer possible on
the command line to use -cpu to ask for a different kind of
CPU than the SoC supports. This was never a supported thing to
do anyway; we were just not sanity-checking the command line.
This does require us to only build the bcm2837 object on
TARGET_AARCH64 configs, since otherwise it won't instantiate
due to the missing cortex-a53 device and "make check" will fail.

The BCM2837 sets the Aff1 field of the MPIDR affinity values for the
CPUs to 0, whereas the BCM2836 uses 0xf. Set this correctly, as it
is required for Linux to boot.

The bcm2837 is pretty similar to the bcm2836, but it does have
some differences. Notably, the MPIDR affinity aff1 values it
sets for the CPUs are 0x0, rather than the 0xf that the bcm2836
uses, and if this is wrong Linux will not boot.
Rather than trying to have one device with properties that
configure it differently for the two cases, create two
separate QOM devices for the two SoCs. We use the same approach
as hw/arm/aspeed_soc.c and share code and have a data table
that might differ per-SoC. For the moment the two types don't
actually have different behaviour.

Our BCM2836 type is really a generic one that can be any of
the bcm283x family. Rename it accordingly. We change only
the names which are visible via the header file to the
rest of the QEMU code, leaving private function names
in bcm2836.c as they are.
This is a preliminary to making bcm283x be an abstract
parent class to specific types for the bcm2836 and bcm2837.

The TypeInfo and state struct for bcm2386 disagree about what the
parent class is -- the TypeInfo says it's TYPE_SYS_BUS_DEVICE,
but the BCM2386State struct only defines the parent_obj field
as DeviceState. This would have caused problems if anything
actually tried to treat the object as a TYPE_SYS_BUS_DEVICE.
Fix the TypeInfo to use TYPE_DEVICE as the parent, since we don't
need any of the additional functionality TYPE_SYS_BUS_DEVICE
provides.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.
