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