Browse source 
init.rc

  on init && property:sys.boot.reason=watchdog,4
     ...

  on init && property:sys.boot.reason=bootloader|recovery|thermal
     ...

Test

  cause->cause = BOARDIOC_RESETCAUSE_CPU_RWDT;
  cause->flag  = 4
  init_main: setprop key:sys.boot.reason value:watchdog,4

  cause->cause = BOARDIOC_RESETCAUSE_CPU_SOFT;
  cause->flag  = BOARDIOC_SOFTRESETCAUSE_ENTER_BOOTLOADER;
  init_main: setprop key:sys.boot.reason value:bootloader
