A developer supplied function to perform platform specific operations. | |
It's a developer supplied function to perform any operations appropriate to a | |

core. Platform developer may modify the SecCoreData passed to PEI Core. | |
It returns a platform specific PPI list that platform wishes to pass to PEI core. | |

PEI core. | |
