arm: drop intermediate cpu_model -> cpu type parsing and use cpu type directly
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.
