|
| 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.
