  19 Abstract:
  20
  21   This file contains a structure definition for the ACPI Memory mapped
  22   configuration space base address Description Table (MCFG).  Any changes
  23   to the MCFG table require updating the respective structure count in
  24   Mcfg.h and then adding the structure to the MCFG defined in this file.
  25   The table layout is defined in Mcfg.h and the table contents are defined
  26   in McfgTable.h and Mcfg.h.
