While trying to build MdeModulePkg for RISCV64, I found a few things that
prevent it from building on architectures besides IA32 and X64 in general.

Daniel Schaefer (3):
  MdeModulePkg: Restrict libraries using SMM to x86
  MdeModulePkg: Set PcdDxeIplSwitchToLongMode false on non-x86
  MdeModulePkg: Use CopyGuid instead of GUID assignment

The modules:

  MdeModulePkg/Bus/Ata/AhciPei/AhciPei.inf
  MdeModulePkg/Bus/Pci/NvmExpressPei/NvmExpressPei.inf
  MdeModulePkg/Universal/Acpi/FirmwarePerformanceDataTableDxe/FirmwarePerformanceDxe.inf

seem like they are independent of SMM but they actually do requires SMM's
LockBoxLib. Ideally they would be rewritten to not require SMM on non x86.

Otherwise the PCD isn't defined on other architectures.

GCC translates a simple assignment to memcpy, which EDKII doesn't provide.

Hi, 

Could you please use CopyMem instead of CopyGuid? Or it will meet following warning with VS compiler.
DeviceManager.c(622): warning C4366: The result of the unary '&' operator may be unaligned

Thanks,
Dandan
