IntelFsp2Pkg: Support Multi-Phase silicon initialization.

[edk2-devel] [PATCH] IntelFsp2Pkg: Support Multi-Phase silicon initialization.

Posted by Chiu, Chasel 3 years, 12 months ago

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2698

To enhance FSP silicon initialization flexibility an
optional Multi-Phase API is introduced and FSP header
needs update for new API offset.
