Hi Chasel,
Looks good! This is mildly unrelated to your change, but could you put a
comment on the following line that informs the reader that 1 == API Mode?
if (PcdGet8 (PcdFspModeSelection) == 1) {
Once that is done... Reviewed-by: Nate DeSimone <nathaniel.l.desim...@intel.com>

Subject: [PATCH] IntelFsp2WrapperPkg: Perform post FSP-S process.
From: "Chasel, Chiu" <chasel.c...@intel.com>
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1716
In API mode FSP wrapper will perform some post FSP-S process but such process
was skipped in Dispatch mode which may impact some of boot loaders.
To align behavior between API and Dispatch, an End-of-Pei callback is
introduced to perform same process in Dispatch mode.
Test: Verified on internal platform and both
FSP API and Dispatch modes booted successfully.
