Siyuan Fu c788c2b1ad UefiCpuPkg: Remove FIT based microcode shadow logic from MpInitLib. ... Commit c7c964b and dd01704 add header file for FIT table and update MpInitLib to support FIT based microcode shadow operation. There are comments that FIT is Intel specific specification instead of industry standard, which should not be placed in EDK2 MdePkg and UefiCpuPkg. So this patch adds a platform PPI for the microcode shadow logic, and remove the FIT related code from EDK2. The FIT based microcode shadow support will be implemented as a new platform PEIM in IntelSiliconPkg in edk2-platforms. This patch doesn't provide a DXE version shadow microcode protocol, a platform which only uses DxeMpInitLib instance only supports PCD based microcode shadowing. A detailed design doc can be found here: https://edk2.groups.io/g/devel/files/Designs/2020/0214/Support%20 the%202nd%20Microcode%20FV%20Flash%20Region.pdf TEST: Tested on FIT enabled platform.
