> Subject: [PATCH v2 5/6] UefiCpuPkg/MpInitLib: Relocate microcode patch
> fields in CPU_MP_DATA
>
> The below 2 microcode patch related fields in structure CPU_MP_DATA:
>
> UINT64 MicrocodePatchAddress;
> UINT64 MicrocodePatchRegionSize;
>
> They will be passed from PEI phase and be reused DXE phase.
>
> Previously, these 2 fields were placed after some fields with type
> 'UINTN', this will lead to different field offset in different
> architecture for them.
>
> This commit will move them before the fields with different size in
> different architecture to ensure they can be properly used in DXE phase.
