/** @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.
