New ARM boards are generally expected to boot their secondary CPUs via the PSCI interface, rather than ad-hoc "loop around in holding pen code" as hw/arm/boot.c implements. In particular this is necessary for mach-virt kernels. For KVM we achieve this by creating the VCPUs with a feature flag marking them as starting in PSCI powered-down state; the guest kernel will then make a PSCI call (implemented in the host kernel) to start the secondaries at an address of its choosing once it has got the primary CPU up. Implement this setting of the feature flag, controlled by a qdev property for ARMCPU, which board code can set if it is a PSCI system.

Linux requires device tree CPU nodes to include a 'compatible' string describing the CPU. Add a field in the ARMCPU struct for this so that boards which construct a device tree can insert the correct CPU nodes. Note that there is currently no officially specified 'compatible' string for the TI925T, Cortex-M3 or SA1110 CPUs.

When the initial SP is loaded from the vector table on ARMv7M systems the two least significant bits are ignored as the stack is always aligned at a four byte boundary (see ARM DDI 0403C, B1.4.1 and B1.5.5). So far QEMU did not ignore these bits leading to a stack alignment inconsitent with real hardware for binaries that rely on this behaviour. This patch fixes this issue by masking the two least significant bits when loading the SP.

Make the 'any' CPU for target-arm available only in linux-user mode. The ARM target provides a CPU named "any", which turns on support for all user-level instruction set extensions we know about. This is intended for linux-user emulation mode, where it is the default CPU type. It makes no sense to try to use this for system emulation, since we don't initialize it with any system-level information like feature register values or implementation specific cp15 registers. (Unsurprisingly, some boards won't boot at all, though you might get lucky in some cases where the guest doesn't happen to prod things that aren't there.) Prevent users from making this command line error by removing the CPU definition from the softmmu build.

Now that ARMCPU is a subclass of DeviceState, we can make the CPU's inbound IRQ and FIQ lines be simply gpio lines, which means we can remove the odd arm_pic shim. We retain the arm_pic_init_cpu() function as a backwards compatibility shim layer so we can convert the board models to get the IRQ and FIQ lines directly from the ARMCPU object one at a time.

Commit c643bed9 moved qemu_init_vcpu() calls to common CPUState code. This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed". The reason for the failure is that CPUClass::kvm_fd is not yet initialized in the following call graph: ->x86_cpu_realizefn ->x86_cpu_apic_realize ->qdev_init ->device_set_realized ->device_reset (hotplugged == 1) ->apic_reset_common ->vapic_base_update ->kvm_apic_vapic_base_update This causes attempted KVM vCPU ioctls to fail. By contrast, in the non-hotplug case the APIC is reset much later, when the vCPU is already initialized. As a quick and safe solution, move the qemu_init_vcpu() call back into the targets' realize functions.

Port the ARM CPU save/load code to use VMState. Some state is saved in a slightly different order to simplify things -- for example arrays are saved one after the other rather than 'striped', and we always save all 32 VFP registers even if the CPU happens to only have 16.

In the initial conversion of CPU models to QOM types, model names were mapped 1:1 to type names. As a side effect this gained us a type "any", which is now a device. To avoid "-device any" silliness and to pave the way for compiling multiple targets into one executable, adopt a <name>-<arch>-cpu scheme. This leads to names like arm926-arm-cpu but is easiest to handle. No functional changes for -cpu arguments or -cpu ? output.
