From fc175434f97d5db518fb6e9a9bfec85e6c166603 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 14 Jun 2015 16:53:15 +0200 Subject: sun6i: cpu_reset: Do not return from cpu_reset() Currently on sun6i after a "reset" the prompt returns and the user can even type stuff until the watchdog triggers and does the actual reset. This is somewhat unexpected behavior for the "reset" command, this commit adds an endless loop to wait for the watchdog to trigger so that we do not return to the prompt.
