7089e0cc46 sysbus: Convert qdev_set_parent_bus() use with Coccinelle, part 4
This is still the same transformation as in the previous commits, but
here the sysbus_init_child_obj() and its matching realize in are in
separate files.  Fortunately, there's just one realize left to
convert.

db873cc5d1 sysbus: Convert qdev_set_parent_bus() use with Coccinelle, part 2
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:

9fc7fc4d39 qom: Less verbose object_initialize_child()
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.

d3bad7e7c4 arm/aspeed: Rework NIC attachment
The number of MACs supported by an Aspeed SoC is defined by "macs_num"
under the SoC model, that is two for the AST2400 and AST2500 and four
for the AST2600. The model initializes the maximum number of supported
MACs but the number of realized devices is capped by the number of
network device back-ends defined on the command line. This can leave
unrealized devices hanging around in the QOM composition tree.

To get virtual hardware that matches the physical hardware, you have
to pass exactly as many -nic options as there are MACs, and some of
them must be -nic none:

* Machines ast2500-evb, palmetto-bmc, romulus-bmc, sonorapass-bmc,
  swift-bmc, and witherspoon-bmc: two -nic, and the second one must be
  -nic none.

* Machine ast2600-evb: four -nic, the first one must be -nic none.

* Machine tacoma-bmc: four nic, the first two and the last one must be
  -nic none.

Modify the machine initialization to define which MACs are attached to
a network device back-end using a bit-field property "macs-mask" and
let the SoC realize all network devices.

The default setting of "macs-mask" is "use MAC0" only, which works for
all our AST2400 and AST2500 machines. The AST2600 machines have
different configurations. The AST2600 EVB machine activates MAC1, MAC2
and MAC3 and the Tacoma BMC machine activates MAC2.

Incompatible CLI change: -nic options now apply to *active* MACs:
MAC1, MAC2, MAC3 for ast2600-evb, MAC2 for tacoma-bmc, and MAC0 for
all the others.

The machines now always get all MACs as they should. Visible in "info
qom-tree", here's the change for tacoma-bmc:

b7f1a0cb76 arm/aspeed: Compute the number of CPUs from the SoC definition
Commit ece09beec4 ("aspeed: introduce a configurable number of CPU
per machine") was a convient change during bringup but the Aspeed SoCs
have a fixed number of CPUs : one for the AST2400 and AST2500, and two
for the AST2600.

When the number of CPUs configured with -smp is less than the SoC's
fixed number, the "unconfigured" CPUs are left unrealized. This can
happen for machines ast2600-evb and tacoma-bmc, where the SoC's fixed
number is 2. To get virtual hardware that matches the physical
hardware, you have to pass -smp cpus=2 (or its sugared form -smp 2).

We normally reject -smp cpus=N when N exceeds the machine's limit.
Except we ignore cpus=2 (and only cpus=2) with a warning for machines
ast2500-evb, palmetto-bmc, romulus-bmc, sonorapass-bmc, swift-bmc, and
witherspoon-bmc.

Remove the "num-cpu" property from the SoC state and use the fixed
number of CPUs defined in the SoC class instead. Compute the default,
min, max number of CPUs of the machine directly from the SoC class
definition.

Machines ast2600-evb and tacoma-bmc now always get their second CPU as
they should. Visible in "info qom-tree"; here's the change for

d2623129a7 qom: Drop parameter @errp of object_property_add() & friends
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().

0e2c24c626 hw/sd: Configure number of slots exposed by the ASPEED SDHCI model
The AST2600 includes a second cut-down version of the SD/MMC controller
found in the AST2500, named the eMMC controller. It's cut down in the
sense that it only supports one slot rather than two, but it brings the
total number of slots supported by the AST2600 to three.

The existing code assumed that the SD controller always provided two
slots. Rework the SDHCI object to expose the number of slots as a
property to be set by the SoC configuration.

46517dd497 Include sysemu/sysemu.h a lot less
In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

hw/qdev-core.h includes sysemu/sysemu.h since recent commit e965ffa70a
"qdev: add qdev_add_vm_change_state_handler()".  This is a bad idea:
hw/qdev-core.h is widely included.

Move the declaration of qdev_add_vm_change_state_handler() to
sysemu/sysemu.h, and drop the problematic include from hw/qdev-core.h.

Touching sysemu/sysemu.h now recompiles some 1800 objects.
qemu/uuid.h also drops from 5400 to 1800.  A few more headers show
smaller improvement: qemu/notify.h drops from 5600 to 5200,
qemu/timer.h from 5600 to 4500, and qapi/qapi-types-run-state.h from
5500 to 5000.

3059c2f5a8 aspeed: Link SCU to the watchdog
The ast2500 uses the watchdog to reset the SDRAM controller. This
operation is usually performed by u-boot's memory training procedure,
and it is enabled by setting a bit in the SCU and then causing the
watchdog to expire. Therefore, we need the watchdog to be able to
access the SCU's register space.

This causes the watchdog to not perform a system reset when the bit is
set. In the future it could perform a reset of the SDMC model.

ones will support SMP. Introduce a new num_cpus field at the SoC class
level to define the number of available CPUs per SoC and also
introduce a 'num-cpus' property to activate the CPUs configured for
the machine.

The max_cpus limit of the machine should depend on the SoC definition
but, unfortunately, these values are not available when the machine
class is initialized. This is the reason why we add a check on
num_cpus in the AspeedSoC realize handler.

SMP support will be activated when models for such SoCs are implemented.

1b0ad56727 hw/arm/aspeed: Use object_initialize_child for correct ref. counting
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):

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());
  }

9b945a9ee3 aspeed/timer: use the APB frequency from the SCU
The timer controller can be driven by either an external 1MHz clock or
by the APB clock. Today, the model makes the assumption that the APB
frequency is always set to 24MHz but this is incorrect.

The AST2400 SoC on the palmetto machines uses a 48MHz input clock
source and the APB can be set to 48MHz. The consequence is a general
system slowdown. The QEMU machines using the AST2500 SoC do not seem
impacted today because the APB frequency is still set to 24MHz.

We fix the timer frequency for all SoCs by linking the Timer model to
the SCU model. The APB frequency driving the timers is now the one
configured for the SoC.

a2e9989c96 hw/arm/aspeed_soc: don't use vmstate_register_ram_global for SRAM
Currently we use vmstate_register_ram_global() for the SRAM;
this is not a good idea for devices, because it means that
you can only ever create one instance of the device, as
the second instance would get a RAM block name clash.
Instead, use memory_region_init_ram(), which automatically
registers the RAM block with a local-to-the-device name.

Note that this would be a cross-version migration compatibility break
for the "palmetto-bmc", "ast2500-evb" and "romulus-bmc" machines,
but migration is currently broken for them.

b6e70d1d7f hw/arm/aspeed: Unlock SCU when running kernel
The ASPEED hardware contains a lock register for the SCU that disables
any writes to the SCU when it is locked. The machine comes up with the
lock enabled, but on all known hardware u-boot will unlock it and leave
it unlocked when loading the kernel.

This means the kernel expects the SCU to be unlocked. When booting from
an emulated ROM the normal u-boot unlock path is executed. Things don't
go well when booting using the -kernel command line, as u-boot does not
run first.

Change behaviour so that when a kernel is passed to the machine, set the
reset value of the SCU to be unlocked.

ba1ba5cca3 arm: drop intermediate cpu_model -> cpu type parsing and use cpu type directly
there are 2 use cases to deal with:
  1: fixed CPU models per board/soc
  2: boards with user configurable cpu_model and fallback to
     default cpu_model if user hasn't specified one explicitly

For the 1st
  drop intermediate cpu_model parsing and use const cpu type
  directly, which replaces:
     typename = object_class_get_name(
           cpu_class_by_name(TYPE_ARM_CPU, cpu_model))
     object_new(typename)
  with
     object_new(FOO_CPU_TYPE_NAME)
  or
     cpu_generic_init(BASE_CPU_TYPE, "my cpu model")
  with
     cpu_create(FOO_CPU_TYPE_NAME)

as result 1st use case doesn't have to invoke not necessary
translation and not needed code is removed.

For the 2nd
 1: set default cpu type with MachineClass::default_cpu_type and
 2: use generic cpu_model parsing that done before machine_init()
    is run and:
    2.1: drop custom cpu_model parsing where pattern is:
       typename = object_class_get_name(
           cpu_class_by_name(TYPE_ARM_CPU, cpu_model))
       [parse_features(typename, cpu_model, &err) ]

    2.2: or replace cpu_generic_init() which does what
         2.1 does + create_cpu(typename) with just
         create_cpu(machine->cpu_type)
as result cpu_name -> cpu_type translation is done using
generic machine code one including parsing optional features
if supported/present (removes a bunch of duplicated cpu_model
parsing code) and default cpu type is defined in an uniform way
within machine_class_init callbacks instead of adhoc places
in boadr's machine_init code.

469f3da42e hw/arm/aspeed_soc: Mark devices as user_creatable = false
QEMU currently aborts if the user is accidentially trying to
do something like this:

 at hw/core/qdev-properties.c:1032:

The ast2400 SoC devices are clearly not creatable by the user since
they are using the serial_hds and nd_table arrays directly in their
realize function, so mark them with user_creatable = false.
