there are 2 use cases to deal with: 1: fixed CPU models per board/soc 2: boards with user configurable cpu_model and fallback to default cpu_model if user hasn't specified one explicitly For the 1st drop intermediate cpu_model parsing and use const cpu type directly, which replaces: typename = object_class_get_name( cpu_class_by_name(TYPE_ARM_CPU, cpu_model)) object_new(typename) with object_new(FOO_CPU_TYPE_NAME) or cpu_generic_init(BASE_CPU_TYPE, "my cpu model") with cpu_create(FOO_CPU_TYPE_NAME) as result 1st use case doesn't have to invoke not necessary translation and not needed code is removed. For the 2nd 1: set default cpu type with MachineClass::default_cpu_type and 2: use generic cpu_model parsing that done before machine_init() is run and: 2.1: drop custom cpu_model parsing where pattern is: typename = object_class_get_name( cpu_class_by_name(TYPE_ARM_CPU, cpu_model)) [parse_features(typename, cpu_model, &err) ] 2.2: or replace cpu_generic_init() which does what 2.1 does + create_cpu(typename) with just create_cpu(machine->cpu_type) as result cpu_name -> cpu_type translation is done using generic machine code one including parsing optional features if supported/present (removes a bunch of duplicated cpu_model parsing code) and default cpu type is defined in an uniform way within machine_class_init callbacks instead of adhoc places in boadr's machine_init code.
