   2 This file contains a structure definition for the ACPI Memory Mapped Configuration
   3 Address Space table (MCFG).  Any changes to the number of entries in the table require
   4 updating the structure count in Mcfg.h and then adding the structure to the
   5 MCFG defined in this file.  The table layout is defined in Mcfg.h and the
   6 table contents are defined in the MemoryMappedConfigurationSpaceAccessTable.h.
