+//      When we IPL a secondary partition, we will check if if the 
+//      secondary xMinPlicVrmIndex > the primary xVrmIndex.  
+//      If it is then this tells PLIC that this secondary is not 
+//      supported running on this "old" of a level of PLIC.
+//
+//      Likewise, we will compare the primary xMinSlicVrmIndex to 
+//      the secondary xVrmIndex. 
+//      If the primary xMinSlicVrmDelta > secondary xVrmDelta then we 
+//      know that this PLIC does not support running an OS "that old".
