* This function must be run after all P-State routines have been executed
*
* @param[in] PsiServices The current CPU's family services.
* @param[in] EntryPoint Timepoint designator.
* @param[in] PlatformConfig Contains the runtime modifiable feature input data.
* @param[in] StdHeader Config handle for library and services.
*
* @retval AGESA_SUCCESS Always succeeds.
