  19   A developer supplied function to perform platform specific operations.
  20
  21   It's a developer supplied function to perform any operations appropriate to a
  22   given platform. It's invoked just before passing control to PEI core by SEC
  23   core. Platform developer may modify the SecCoreData passed to PEI Core.
  24   It returns a platform specific PPI list that platform wishes to pass to PEI core.
  25   The Generic SEC core module will merge this list to join the final list passed to
  26   PEI core.
  27
  28   @param[in,out] SecCoreData           The same parameter as passing to PEI core. It
  29                                        could be overridden by this function.
  30
  31   @return The platform specific PPI list to be passed to PEI core or
  32           NULL if there is no need of such platform specific PPI list.
