/** @file
|
This file describes the contents of the ACPI Multiple APIC Description
|
Table (MADT). Some additional ACPI values are defined in Acpi10.h and
|
Acpi20.h.
|
To make changes to the MADT, it is necessary to update the count for the
|
APIC structure being updated, and to modify table found in Madt.c.
