[PATCH v3 14/32] target/rx: Use generic helper to show CPU model names

Posted by Gavin Shan 1 year, 2 months ago

For target/rx, the CPU type name can be: (1) the combination of the
CPU model name and suffix; (2) same to the CPU model name. The CPU
type names have been shown in rx_cpu_list_entry().

Use generic helper cpu_model_from_type() to show the CPU model names
in rx_cpu_list_entry(). Besides, rx_cpu_class_by_name() is improved
by merging the condition of '@oc == NULL' to object_class_dynamic_cast().
