  # 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
  #
  #   PcdPciIoTranslation     = IoCpuBase     - PcdPciIoBase;
  #   PcdPciMmio32Translation = Mmio32CpuBase - (UINT64)PcdPciMmio32Base;
  #   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 +
  #                             PcdPciIoTranslation;
  #   TranslatedMmio32Address = (UINT64)UntranslatedMmio32Address +
  #                             PcdPciMmio32Translation;
  #   TranslatedMmio64Address = UntranslatedMmio64Address +
  #                             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
  #  PcdPciMmio64Base.
