Re: [PATCH] IntelFsp2WrapperPkg: Perform post FSP-S process.

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.desimone@intel.com>

Subject: [PATCH] IntelFsp2WrapperPkg: Perform post FSP-S process.

From: "Chasel, Chiu" <chasel.chiu@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.
