[v4,21/33] target/hppa: Implement hppa_cpu_list()

Commit Message

Gavin Shan Nov. 2, 2023, 12:24 a.m. UTC

Implement hppa_cpu_list() to support cpu_list(). With this applied,
the available CPU model names, same to the CPU type names, are shown
as below.

  $ ./build/qemu-system-hppa -cpu ?
  Available CPUs:
    hppa-cpu
