- Add a vendor command that provides alert counter. Userspace can use it e.g. for user metric analysis. - Add 'alerts' debug console command. It provides information about chip alerts: supported alerts, fuse status, interrupt status, alert counter. - Add 'alerts fire [INT]' command to fire a software defined alert (globalsec/fwN where N is 0,1,2,3).
