[PATCH v3 22/32] target/nios2: Implement nios2_cpu_list()

Posted by Gavin Shan 1 year, 2 months ago

Implement nios2_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-nios2 -cpu ?
  Available CPUs:
    nios2-cpu
