If changing this comment anyway, I'd suggest removing particular SoC 
series from it and also correct writing style. My suggestion is:

/*
  * Prepare the CPU for shutting down. The required sequence of
  * operations depends on core type. CPUID part number can be used to
  * determine the right way.
  */

Best regards,
Tomasz
