  42   ## Pcd8259LegacyModeMask defines the default mask value for platform. This value is determined
  43   #  1) If platform only support pure UEFI, value should be set to 0xFFFF or 0xFFFE;
  44   #     Because only clock interrupt is allowed in legacy mode in pure UEFI platform.
  45   #  2) If platform install CSM and use thunk module:
  46   #     a) If thunk call provided by CSM binary requires some legacy interrupt support, the corresponding bit
  47   #        should be opened as 0.
  48   #        For example, if keyboard interfaces provided CSM binary use legacy keyboard interrupt in 8259 bit 2, then
  49   #        the value should be set to 0xFFFC
  50   #     b) If all thunk call provied by CSM binary do not require legacy interrupt support, value should be set
  51   #        to 0xFFFF or 0xFFFE.
  52   #
  53   #  The default value of legacy mode mask could be changed by EFI_LEGACY_8259_PROTOCOL->SetMask(). But it is rarely
  54   #  need change it except some special cases such as when initializing the CSM binary, it should be set to 0xFFFF to
  55   #  mask all legacy interrupt. Please restore the original legacy mask value if changing is made for these special case.
