The crash command is used to intentionally invoke various failure modes in a running system. This adds one more (and cleans up the command slightly). The "crash hang" command does the same thing as "crash watchdog", except that it disables interrupts first. Some SoCs may require special handling to recover from that case. BUG=none BRANCH=none TEST=make buildall; run on Cr50 hardware Invoked all the options to the crash command, observed that the appropriate response occurred in each case (a stack trace if possible, followed by a reboot).
