2020-10-18uninorth: use qdev gpios for PCI IRQsMark Cave-Ayland
Currently an object link property is used to pass a reference to the OpenPIC into the PCI host bridge so that pci_unin_init_irqs() can connect the PCI IRQs to the PIC itself. This can be simplified by defining the PCI IRQs as qdev gpios and then wiring up the PCI IRQs to the PIC in the New World machine init function.

2020-10-12device-core: use atomic_set on .realized propertyMaxim Levitsky
Some code might race with placement of new devices on a bus. We currently first place a (unrealized) device on the bus and then realize it. As a workaround, users that scan the child device list, can check the realized property to see if it is safe to access such a device. Use an atomic write here too to aid with this. A separate discussion is what to do with devices that are unrealized: It looks like for this case we only call the hotplug handler's unplug callback and its up to it to unrealize the device. An atomic operation doesn't cause harm for this code path though.

2020-10-12qdev: add "check if address free" callback for busesPaolo Bonzini
Check if an address is free on the bus before plugging in the device. This makes it possible to do the check without any side effects, and to detect the problem early without having to do it in the realize callback.

2020-10-12hw/nvram: Always register FW_CFG_DATA_GENERATOR_INTERFACEPhilippe Mathieu-Daudé
While the FW_CFG_DATA_GENERATOR_INTERFACE is only consumed by a device only available using system-mode (fw_cfg), it is implemented by a crypto component (tls-cipher-suites) which is always available when crypto is used. Commit 69699f3055 introduced the following error in the qemu-storage-daemon binary: $ echo -e \ '{"execute": "qmp_capabilities"}\r\n{"execute": "qom-list-types"}\r\n{"execute": "quit"}\r\n' \ | storage-daemon/qemu-storage-daemon --chardev stdio,id=qmp0 --monitor qmp0 {"QMP": {"version": {"qemu": {"micro": 50, "minor": 1, "major": 5}, "package": ""}, "capabilities": ["oob"]}} {"return": {}} missing interface 'fw_cfg-data-generator' for object 'tls-creds' Aborted (core dumped) Since QOM dependencies are resolved at runtime, this issue could not be triggered at linktime, and we don't have test running the qemu-storage-daemon binary. Fix by always registering the QOM interface.

In commit 102ca9667d we set "start-powered-off" on all vCPUs included in the CPS (Coherent Processing System) but forgot to start the vCPUS on when they are powered on in the CPC (Cluster Power Controller).
