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