+	  Set this number to the maximum number of possible CPUs in the SoC.
+	  SoCs may have multiple clusters with each cluster may have multiple
+	  ports. If some ports are reserved but higher ports are used for
+	  cores, count the reserved ports. This will allocate enough memory
+	  in spin table to properly handle all cores.
