dadd1a0809 hw/arm/smmuv3: Queue helpers
We introduce helpers to read/write into the command and event
circular queues.

smmuv3_write_eventq and smmuv3_cmq_consume will become static
in subsequent patches.

Invalidation commands are not yet dealt with. We do not cache
data that need to be invalidated. This will change with vhost
integration.

6a736033d3 hw/arm/smmuv3: Wired IRQ and GERROR helpers
We introduce some helpers to handle wired IRQs and especially
GERROR interrupt. SMMU writes GERROR register on GERROR event
and SW acks GERROR interrupts by setting GERRORn.

The Wired interrupts are edge sensitive hence the pulse usage.

cac994ef43 hw/arm/smmu-common: IOMMU memory region and address space setup
We set up the infrastructure to enumerate all the PCI devices
attached to the SMMU and create an associated IOMMU memory
region and address space.

Those info are stored in SMMUDevice objects. The devices are
grouped according to the PCIBus they belong to. A hash table
indexed by the PCIBus pointer is used. Also an array indexed by
the bus number allows to find the list of SMMUDevices.

When running omap1/2 or pxa2xx based ARM machines with -nodefaults,
they bail out immediately complaining about a "missing SecureDigital

default devices. So let's turn the error message and exit() into

0c9492765a arm: boot: set boot_info starting from first_cpu
Even though nothing is currently broken (since all boards
use first_cpu as boot cpu), make sure that boot_info is set
on all CPUs.
If some board would like support heterogenuos setup (i.e.
init boot_info on subset of CPUs) in future, it should add
a reasonable API to do it, instead of starting assigning
boot_info from some CPU and till the end of present CPUs
list.

6d9c1b8dbb hw/arm/virt: Add linux,pci-domain property
This allows to pin the host controller in the Linux PCI domain space.
Linux requires that property to be available consistently or not at all,
in which case the domain number becomes unstable on additions/removals.
Adding it here won't make a difference in practice for most setups as we
only expose one controller.

However, enabling Jailhouse on top may introduce another controller, and
that one would like to have stable address as well. So the property is
needed for the first controller as well.

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.

b901a17245 hw/arm/raspi: Don't bother setting default_cpu_type
In commit 210f47840d, we changed the bcm2836 SoC object to
always create a CPU of the correct type for that SoC model. This
makes the default_cpu_type settings in the MachineClass structs
for the raspi2 and raspi3 boards redundant. We didn't change
those at the time because it would have meant a temporary
regression in a corner case of error handling if the user
requested a non-existing CPU type. The -cpu parse handling
changes in 2278b93941 mean that it no longer implicitly
depends on default_cpu_type for this to work, so we can now
delete the redundant default_cpu_type fields.

with partially set do_cpu_reset() callback leaving some CPUs without it.

Make sure that do_cpu_reset() is registered for all CPUs by enumerating
CPUs from first_cpu.

(In practice every board that we have was passing us the first CPU
as the boot CPU, either directly or indirectly, so this wasn't
causing incorrect behaviour.)

f640a5914f hw/arm/fsl-imx: Fix introspection problem with fsl-imx6 and fsl-imx7
QEMU currently exits unexpectedly when trying to introspect the fsl-imx6
and fsl-imx7 devices on systems with many SMP CPUs:

$ echo "{'execute':'qmp_capabilities'}"\
       "{'execute':'device-list-properties',"\
       " 'arguments':{'typename':'fsl,imx6'}}" \
       | arm-softmmu/qemu-system-arm -M virt,accel=qtest -qmp stdio -smp 8
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
 "package": "build-all"}, "capabilities": []}}
{"return": {}}
fsl,imx6: Only 4 CPUs are supported (8 requested)

And:

$ echo "{'execute':'qmp_capabilities'}"\
       "{'execute':'device-list-properties',"\
       " 'arguments':{'typename':'fsl,imx7'}}" \
       | arm-softmmu/qemu-system-arm -M raspi2,accel=qtest -qmp stdio

 "package": "build-all"}, "capabilities": []}}
{"return": {}}
fsl,imx7: Only 2 CPUs are supported (4 requested)

This happens because these devices are doing an exit() from their
instance_init function - which should never be done since instance_init
can be called at any time for device introspection! Fix it by moving
the deadly check into the realize() function instead.

8aabc5437b hw/arm/allwinner-a10: Do not use nd_table in instance_init function
The instance_init function of a device can be called at any time, even
if the device is not going to be used (i.e. not going to be realized).
So a instance_init function must not do things that could cause QEMU
to exit, like calling qemu_check_nic_model(&nd_table[0], ...) for example.
But this is what the instance_init function of the allwinner-a10 device
is currently doing - and this causes QEMU to quit unexpectedly when
you run the 'device-list-properties' QMP command for example:

$ echo "{'execute':'qmp_capabilities'}"\
       "{'execute':'device-list-properties',"\
       " 'arguments':{'typename':'allwinner-a10'}}" \
       | arm-softmmu/qemu-system-arm -M mps2-an505,accel=qtest -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
 "package": "build-all"}, "capabilities": []}}
{"return": {}}
Unsupported NIC model: lan9118

... and QEMU quits after printing the last line (which should not happen
just because of running 'device-list-properties' here).

And with the cubieboard, this even causes QEMU to abort():

$ echo "{'execute':'qmp_capabilities'}"\
       "{'execute':'device-list-properties',"\
       " 'arguments':{'typename':'allwinner-a10'}}" \
       | arm-softmmu/qemu-system-arm -M cubieboard,accel=qtest -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
 "package": "build-all"}, "capabilities": []}}
{"return": {}}
Unexpected error in error_set_from_qdev_prop_error() at hw/core/qdev-properties.c:1095:
Property 'allwinner-emac.netdev' can't take value 'hub0port0', it's in use

To fix the problem we've got to move the offending code to the realize

ff72cb6b46 hw/arm/raspi: Provide spin-loop code for AArch64 CPUs
The raspi3 has AArch64 CPUs, which means that our smpboot
code for keeping the secondary CPUs in a pen needs to have
a version for A64 as well as A32. Without this, the
secondary CPUs go into an infinite loop of taking undefined
instruction exceptions.

210f47840d hw/arm/bcm2836: Hardcode correct CPU type
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.

0fd74f03ed hw/arm/bcm2836: Create proper bcm2837 device
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.

926dcdf073 hw/arm/bcm2836: Rename bcm2836 type/struct to bcm283x
Our BCM2836 type is really a generic one that can be any of

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.

3d260cf3c6 hw/arm/bcm2386: Fix parent type of bcm2386
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.

43118f4351 hw/arm/boot: assert that secure_boot and secure_board_setup are false for AArch64
Add some assertions that if we're about to boot an AArch64 kernel,
the board code has not mistakenly set either secure_boot or
secure_board_setup. It doesn't make sense to set secure_boot,
because all AArch64 kernels must be booted in non-secure mode.

It might in theory make sense to set secure_board_setup, but
we don't currently support that, because only the AArch32
bootloader[] code calls this hook; bootloader_aarch64[] does not.
Since we don't have a current need for this functionality, just
assert that we don't try to use it. If it's needed we'll add
it later.

Add support for passing 'max' to -machine gic-version. By analogy
with the -cpu max option, this picks the "best available" GIC version
whether you're using KVM or TCG, so it behaves like 'host' when
using KVM, and gives you GICv3 when using TCG.

Also like '-cpu host', using -machine gic-version=max' means there
is no guarantee of migration compatibility between QEMU versions;
in future 'max' might mean '4'.
