This is the same transformation as in the previous commit, except
sysbus_init_child_obj() and realize are too separated for the commit's
Coccinelle script to handle, typically because sysbus_init_child_obj()
is in a device's instance_init() method, and the matching realize is
in its realize() method.
Perhaps a Coccinelle wizard could make it transform that pattern, but
I'm just a bungler, and the best I can do is transforming the two
separate parts separately:

This script is *unsound*: we need to manually verify init and realize
conversions are properly paired.
This commit has only the pairs where object_initialize_child()'s
@child and sysbus_realize()'s @dev argument text match exactly within
the same source file.

All users of object_initialize_child() pass the obvious child size
argument. Almost all pass &error_abort and no properties. Tiresome.
Rename object_initialize_child() to
object_initialize_child_with_props() to free the name. New
convenience wrapper object_initialize_child() automates the size
argument, and passes &error_abort and no properties.
Rename object_initialize_childv() to
object_initialize_child_with_propsv() for consistency.
Convert callers with this Coccinelle script:

In my "build everything" tree, changing hw/qdev-properties.h triggers
a recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).
Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h. Include hw/qdev-core.h there
instead.
hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.
While there, delete a few superfluous inclusions of hw/qdev-core.h.
Touching hw/qdev-properties.h now recompiles some 1200 objects.

As explained in commit aff39be0ed97:
Both functions, object_initialize() and object_property_add_child()
increase the reference counter of the new object, so one of the
references has to be dropped afterwards to get the reference
counting right. Otherwise the child object will not be properly
cleaned up when the parent gets destroyed.
Thus let's use now object_initialize_child() instead to get the
reference counting here right.
This patch was generated using the following Coccinelle script
(with a bit of manual fix-up for overly long lines):
@use_object_initialize_child@
expression parent_obj;
expression child_ptr;
expression child_name;
expression child_type;
expression child_size;
expression errp;
@@
(
- object_initialize(child_ptr, child_size, child_type);
+ object_initialize_child(parent_obj, child_name, child_ptr, child_size,
+ child_type, &error_abort, NULL);
... when != parent_obj
- object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), NULL);
...
?- object_unref(OBJECT(child_ptr));
|
- object_initialize(child_ptr, child_size, child_type);
+ object_initialize_child(parent_obj, child_name, child_ptr, child_size,
+ child_type, errp, NULL);
... when != parent_obj
- object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), errp);
...
?- object_unref(OBJECT(child_ptr));
)
While the object_initialize() function doesn't take an
'Error *errp' argument, the object_initialize_child() does.
Since this code is used when a machine is created (and is not
yet running), we deliberately choose to use the &error_abort
argument instead of ignoring errors if an object creation failed.

This patch was generated using the following Coccinelle script
(then manually modified to use numbered IPI name)
@use_sysbus_init_child_obj_missing_parent@
expression child_ptr;
expression child_type;
expression child_size;
@@

We let the SoC adopt the IPI children.

'Error *errp' argument, the object_initialize_child() does.
Since this code is used when a machine is created (and is not

argument instead of ignoring errors if an object creation failed.
This choice also matches when using sysbus_init_child_obj(),
since its code is:
void sysbus_init_child_obj(Object *parent,
const char *childname, void *child,
size_t childsize, const char *childtype)
{
object_initialize_child(parent, childname, child, childsize,
childtype, &error_abort, NULL);
qdev_set_parent_bus(DEVICE(child), sysbus_get_default());

The Inter Processor Interrupt is a block part of the SoC, not the
"machine" (talking about machine is borderline with the PMU, since
it is embedded into the ZynqMP SoC, but currentl QEMU doesn't
support multi-arch cores).
Move the IPI state to the SoC state, this will simplify the review
of the next patch.

The Xilinx ZynqMP SoC has two main processing systems in it. The ARM
processing system (which is already modeled in QEMU) and the MicroBlaze
Power Management Unit (PMU). This is the inital work for adding support
for the PMU.
The PMU susbsystem runs along side the ARM system on hardware, but due
to architecture limitations in QEMU the two instances are seperate for
the time being.
Let's follow the same setup we do with the ARM system, where there is an
SoC device and a ZCU102 board. Although the PMU is less board specific
we are still going to follow the same split as maybe in future we can
connect the PMU device to the ARM ZCU102 board. As the machine will be
fairly small let's keep them both together in one file.
