The firmware field used to detect CAS reboots (ibm,fw-nbr-reboots) is 
really a private
field that could change without warning.  A new field 
ibm,#reconfig-reboots will be
added as a public interface intended to be used for this detection.  The 
patch will first
check for ibm,#reconfig-reboots if that is not found it will see if 
ibm,fw-nbr-reboots
is present and will use that instead.
