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.
 */
