/** @file
|
||
|
|
This file contains a structure definition for the ACPI Memory Mapped Configuration
|
||
|
|
Address Space table (MCFG). Any changes to the number of entries in the table require
|
||
|
|
updating the 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 the MemoryMappedConfigurationSpaceAccessTable.h.
