+         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.
