| 14 | \r | |
| 15 | This file contains a structure definition for the ACPI Memory mapped\r | |
| 16 | configuration space base address Description Table (MCFG). Any changes\r | |
| 17 | to the MCFG table require updating the respective structure count in\r | |
| 18 | Mcfg.h and then adding the structure to the MCFG defined in this file.\r | |
| 19 | The table layout is defined in Mcfg.h and the table contents are defined\r | |
| 20 | in McfgTable.h and Mcfg.h.\r | |
