When PiSmmCore links against PeiDxeDebugLibReportStatusCode, the code flow below will cause a FreePool() assertion issue. PiSmmCoreMemoryAllocationLibConstructor() -> SmmInitializeMemoryServices() -> DEBUG ((DEBUG_INFO, "SmmAddMemoryRegion\n")) in SmmAddMemoryRegion() -> DebugPrint() -> REPORT_STATUS_CODE_EX() -> ReportStatusCodeEx() -> AllocatePool()/FreePool(PiSmmCoreMemoryAllocLib) -> ASSERT() at Head = CR (Buffer, POOL_HEAD, Data, POOL_HEAD_SIGNATURE) in CoreFreePoolI() of DxeCore Pool.c It is because at the point of FreePool() in the code flow above, mSmmCoreMemoryAllocLibSmramRanges/mSmmCoreMemoryAllocLibSmramRangeCount are not been initialized yet, the FreePool() will be directed to gBS->FreePool(), that is wrong. This patch is to temporarily use BootServicesData to hold the SmramRanges data before calling SmmInitializeMemoryServices().
