hw/arm/raspi: Remove obsolete use of -smp to set the soc 'enabled-cpus'
Since we enabled parallel TCG code generation for softmmu (see commit 3468b59 "tcg: enable multiple TCG contexts in softmmu") and its subsequent fix (commit 72649619 "add .min_cpus and .default_cpus fields to machine_class"), the raspi machines are restricted to always use their 4 cores: See in hw/arm/raspi2 (with BCM283X_NCPUS set to 4): 222 static void raspi2_machine_init(MachineClass *mc) 223 { 224 mc->desc = "Raspberry Pi 2"; 230 mc->max_cpus = BCM283X_NCPUS; 231 mc->min_cpus = BCM283X_NCPUS; 232 mc->default_cpus = BCM283X_NCPUS; 235 }; 236 DEFINE_MACHINE("raspi2", raspi2_machine_init) We can no longer use the -smp option, as we get: $ qemu-system-arm -M raspi2 -smp 1 qemu-system-arm: Invalid SMP CPUs 1. The min CPUs supported by machine 'raspi2' is 4 Since we can not set the TYPE_BCM283x SOC "enabled-cpus" with -smp, remove the unuseful code. We can achieve the same by using the '-global bcm2836.enabled-cpus=1' option.
