+ 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.
