The 'stm32vldiscovery' machine ignores the CPU type requested by the command line. This might confuse users, since the following will create a machine with a Cortex-M3 CPU: $ qemu-system-aarch64 -M stm32vldiscovery -cpu neoverse-n1 Set the MachineClass::valid_cpu_types field (introduced in commit c9cf636d48 "machine: Add a valid_cpu_types property"). Remove the now unused MachineClass::default_cpu_type field. We now get: $ qemu-system-aarch64 -M stm32vldiscovery -cpu neoverse-n1 qemu-system-aarch64: Invalid CPU type: neoverse-n1-arm-cpu The valid types are: cortex-m3-arm-cpu Since the SoC family can only use Cortex-M3 CPUs, hard-code the CPU type name at the SoC level, removing the QOM property entirely.
