[PATCH 0/3] hw/arm/virt: Use generic CPU invalidation

[Gavin Shan]

There is a generic CPU type invalidation in machine_run_board_init()
and we needn't a same and private invalidation for hw/arm/virt machines.
This series intends to use the generic CPU type invalidation on the
hw/arm/virt machines.

PATCH[1] factors the CPU type invalidation logic in machine_run_board_init()
         to a helper validate_cpu_type().
PATCH[2] uses the generic CPU type invalidation for hw/arm/virt machines
PATCH[3] support "host-arm-cpu" CPU type only when KVM or HVF is visible

Testing
=======

With the following command lines, the output messages are varied before
and after the series is applied.

  /home/gshan/sandbox/src/qemu/main/build/qemu-system-aarch64 \
  -accel tcg -machine virt,gic-version=3,nvdimm=on            \
  -cpu cortex-a8 -smp maxcpus=2,cpus=1                        \
    :

Before the series is applied:

  qemu-system-aarch64: mach-virt: CPU type cortex-a8-arm-cpu not supported

After the series is applied:

  qemu-system-aarch64: Invalid CPU type: cortex-a8-arm-cpu
  The valid types are: cortex-a7-arm-cpu, cortex-a15-arm-cpu, \
  cortex-a35-arm-cpu, cortex-a55-arm-cpu, cortex-a72-arm-cpu, \
  cortex-a76-arm-cpu, a64fx-arm-cpu, neoverse-n1-arm-cpu,     \
  neoverse-v1-arm-cpu, cortex-a53-arm-cpu, cortex-a57-arm-cpu, \
  max-arm-cpu

  machine: Factor CPU type invalidation out into helper
  hw/arm/virt: Use generic CPU type invalidation
  hw/arm/virt: Support host CPU type only when KVM or HVF is configured
