   # Bases, sizes and translation offsets of IO and MMIO spaces, respectively.
   # Note that "IO" is just another MMIO range that simulates IO space; there
   # are no special instructions to access it.
   #
   # The base addresses PcdPciIoBase, PcdPciMmio32Base and PcdPciMmio64Base are
   # specific to their containing address spaces. In order to get the physical
   # address for the CPU, for a given access, the respective translation value
   # has to be added.
   #
   # The translations always have to be initialized like this, using UINT64:
   #
   #   UINT64 IoCpuBase;     // mapping target in 64-bit cpu-physical space
   #   UINT64 Mmio32CpuBase; // mapping target in 64-bit cpu-physical space
   #   UINT64 Mmio64CpuBase; // mapping target in 64-bit cpu-physical space
   #
   #   gEfiMdePkgTokenSpaceGuid.PcdPciIoTranslation = IoCpuBase - PcdPciIoBase;
   #   gEfiMdePkgTokenSpaceGuid.PcdPciMmio32Translation = Mmio32CpuBase - (UINT64)PcdPciMmio32Base;
   #   gEfiMdePkgTokenSpaceGuid.PcdPciMmio64Translation = Mmio64CpuBase - PcdPciMmio64Base;
   #
   # because (a) the target address space (ie. the cpu-physical space) is
   # 64-bit, and (b) the translation values are meant as offsets for *modular*
   # arithmetic.
   #
   # Accordingly, the translation itself needs to be implemented as:
   #
   #   UINT64 UntranslatedIoAddress;     // input parameter
   #   UINT32 UntranslatedMmio32Address; // input parameter
   #   UINT64 UntranslatedMmio64Address; // input parameter
   #
   #   UINT64 TranslatedIoAddress;       // output parameter
   #   UINT64 TranslatedMmio32Address;   // output parameter
   #   UINT64 TranslatedMmio64Address;   // output parameter
   #
   #   TranslatedIoAddress     = UntranslatedIoAddress +
   #                             gEfiMdePkgTokenSpaceGuid.PcdPciIoTranslation;
   #   TranslatedMmio32Address = (UINT64)UntranslatedMmio32Address +
   #                             gEfiMdePkgTokenSpaceGuid.PcdPciMmio32Translation;

   #                             gEfiMdePkgTokenSpaceGuid.PcdPciMmio64Translation;
   #
   #  The modular arithmetic performed in UINT64 ensures that the translation
   #  works correctly regardless of the relation between IoCpuBase and
   #  PcdPciIoBase, Mmio32CpuBase and PcdPciMmio32Base, and Mmio64CpuBase and

	# has to be added.

	# UINT64 IoCpuBase; // mapping target in 64-bit cpu-physical space
	# UINT64 Mmio32CpuBase; // mapping target in 64-bit cpu-physical space
	# UINT64 Mmio64CpuBase; // mapping target in 64-bit cpu-physical space

	# because (a) the target address space (ie. the cpu-physical space) is
	# 64-bit, and (b) the translation values are meant as offsets for modular
	# arithmetic.
	#
	# Accordingly, the translation itself needs to be implemented as:
	#
	# UINT64 UntranslatedIoAddress; // input parameter
	# UINT32 UntranslatedMmio32Address; // input parameter
	# UINT64 UntranslatedMmio64Address; // input parameter
	#

	# UINT64 TranslatedMmio32Address; // output parameter
