The Aspeed Watchdog and Timer models have a link pointing to the SCU
controller model of the machine.
Change the "scu" property definition so that it explicitly sets the
pointer. The property isn't optional : not being able to set the link
is a bug and QEMU should rather abort than exit in this case.

The I2C controller of the Aspeed AST2500 and AST2600 SoCs supports DMA
transfers to and from DRAM.
A pair of registers defines the buffer address and the length of the
DMA transfer. The address should be aligned on 4 bytes and the maximum
length should not exceed 4K. The receive or transmit DMA transfer can
then be initiated with specific bits in the Command/Status register of
the controller.

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.

introduce a 'num-cpus' property to activate the CPUs configured for

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.

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);
...

|

... when != parent_obj
- object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), errp);
...
?- object_unref(OBJECT(child_ptr));
)
@use_sysbus_init_child_obj@
expression parent_obj;
expression dev;
expression child_ptr;
expression child_name;
expression child_type;
expression child_size;
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());
}

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.

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,

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.

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

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.

Add a new configuration field at the board level and propagate the
value using the "num-cs" property of the FMC controller model.

There is not much differences with the A0 revision apart from the DDR
calibration.

The size of the SRAM depends on the SoC model, so use a per-soc
definition when creating the region.

With commit ce5b1bbf62 ("exec: move cpu_exec_init() calls to realize
functions"), we can now remove cannot_destroy_with_object_finalize_yet.

The SMC controllers on the Aspeed AST2500 SoC are very similar to the
ones found on the AST2400. The differences are on the number of
supported flash modules and their default mappings in the SoC address
space.
The Aspeed AST2500 has one SPI controller for the BMC firmware and two
for the host firmware. All controllers have now the same set of
registers compatible with the AST2400 FMC controller and the legacy
'SMC' controller is fully gone.
We keep the FMC object to act as the BMC SPI controller and add a new
SPI controller for the host. We also have to introduce new type names
to handle the differences in the flash modules memory mappping.

The AST2500 SoC has two. Let's prepare ground for the next changes
which will add the required definitions for the second host SPI
controller.
