      6 # Reload script
      7 #
      8 #	A system reload is when the software is restarted from scratch
      9 #	*without* the hardware being reset in any way.  The software
     10 #	will read the current state out of the hardware and resume as if
     11 #	nothing had happened.
     12 #
     13 #	This script is the reload counterpart to the rc.soc script.
     14 #	It calls all the steps needed during the reload process to
     15 #	restore each subsystem.
     16 #
     17 #	To use reload mode, the boot flag must be set to indicate reload.
     18 #	In this mode, the BCM command monitor will attach all devices
     19 #	and come to the prompt non-destructively.  Then this script is
     20 #	run to bring all the software modules through reload initialization.
     21 #	
     22 #	Assumes the same board configuration config variables are set
     23 #	that rc.soc uses.
