As explained in commit aff39be0ed:
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);
...

@use_sysbus_init_child_obj@
expression parent_obj;
expression dev;

expression errp;
@@
(
- object_initialize_child(parent_obj, child_name, child_ptr, child_size,
- child_type, errp, NULL);
+ sysbus_init_child_obj(parent_obj, child_name, child_ptr, child_size,
+ child_type);
...
- qdev_set_parent_bus(DEVICE(child_ptr), sysbus_get_default());
|
- object_initialize_child(parent_obj, child_name, child_ptr, child_size,
- child_type, errp, NULL);
+ sysbus_init_child_obj(parent_obj, child_name, child_ptr, child_size,
+ child_type);
- dev = DEVICE(child_ptr);
- qdev_set_parent_bus(dev, sysbus_get_default());
)
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 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());
}

To be coherent with the other peripherals contained in the
BCM2835PeripheralState structure, directly allocate the PL011State
(instead of using the pl011 uart as a pointer to a SysBusDevice).
Initialize the PL011State with object_initialize() instead of
object_new().

Recent vanilla Raspberry Pi kernels started to make use of
the hardware random number generator in BCM2835 SoC. As a
result, those kernels wouldn't work anymore under QEMU
but rather just freeze during the boot process.
This patch implements a trivial BCM2835 compatible RNG,
and adds it as a peripheral to BCM2835 platform, which
allows to boot a vanilla Raspberry Pi kernel under Qemu.
Changes since v1:
* Prevented guest from writing [31..20] bits in rng_status
* Removed redundant minimum_version_id_old
* Added field entries for the state
* Changed realize function to reset

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.

Return a valid value from the BCM2835 property mailbox query "get board
revision". This query is used by U-Boot. Implementing it fixes the first
obvious difference between qemu and real HW.
The value returned is currently hard-coded to match the RPi2 I own. Other
values are legal, e.g. different board manufacturer field values are
likely to exist in the wild.
