This series bases on Phil's repository because the prepatory commits
have been queued to the branch.

  https://gitlab.com/philmd/qemu.git (branch: cpus-next)

There are two places where the user specified CPU type is checked to see
if it's supported or allowed by the board: machine_run_board_init() and
mc->init(). We don't have to maintain two duplicate sets of logic. This
series intends to move the check to machine_run_board_init() so that we
have unified CPU type check.

This series can be checked out from:

  git@github.com:gwshan/qemu.git (branch: kvm/cpu-type)

PATCH[1-4] refactors and improves the logic to validate CPU type in
           machine_run_board_init()
PATCH[5-9] validates the CPU type in machine_run_board_init() for the
           individual boards

Testing
=======

Before the series is applied:

  [gshan@gshan q]$ ./build/qemu-system-aarch64 -M virt -cpu cortex-a8
  qemu-system-aarch64: mach-virt: CPU type cortex-a8-arm-cpu not supported
  [gshan@gshan q]$ ./build/qemu-system-aarch64 -M sbsa-ref -cpu cortex-a53
  qemu-system-aarch64: sbsa-ref: CPU type cortex-a53-arm-cpu not supported
  [gshan@gshan q]$ ./build/qemu-system-aarch64 -M sbsa-ref -cpu sa1100
  qemu-system-aarch64: sbsa-ref: CPU type sa1100-arm-cpu not supported
  [gshan@gshan q]$ ./build/qemu-system-aarch64 -M sbsa-ref -cpu host
  qemu-system-aarch64: unable to find CPU model 'host'

After the series is applied:

  [gshan@gshan q]$ ./build/qemu-system-aarch64 -M virt -cpu cortex-a8
  qemu-system-aarch64: Invalid CPU model: cortex-a8
  The valid models are: cortex-a7, cortex-a15, cortex-a35, cortex-a55,     \
                        cortex-a72, cortex-a76, cortex-a710, a64fx,        \

Changelog
=========
v8:
  * Pick r-bs from Phil                                          (Gavin)
  * Drop @local_err and use @errp in machine_run_board_init()    (Phil)
  * Add PATCH[v8 3/9] to improve is_cpu_type_supported()         (Phil)
  * Use g_autofree and replace 'type' with 'model' for the
    error messages in is_cpu_type_supported()                    (Phil)
v7:
  * Add 'return' after error_propagate() in machine_run_board_init()
    to avoid calling mc->init() in the failing case              (Marcin)
v6:
  * Drop PATCH[v5 01-23], queued by Phil                         (Phil)
  * Clearer hint if only one CPU type is supported and have
    'const MachineState *' in is_cpu_type_supported()            (Phil)
  * Move valid_cpu_types[] to board's class_init() function      (Phil)
