- Abstract:
- This file contains a structure definition for the ACPI Memory mapped
- configuration space base address Description Table (MCFG). Any changes
- to the MCFG table require updating the respective structure count in
- Mcfg.h and then adding the structure to the MCFG defined in this file.
- The table layout is defined in Mcfg.h and the table contents are defined
- in McfgTable.h and Mcfg.h.
