+ * This table is responsible for physically routing the PIC and
+ * IOAPIC IRQs to the different PCI devices on the system.  It
+ * is read and written via registers 0xC00/0xC01 as an
+ * Index/Data pair.  These values are chipset and mainboard
+ * dependent and should be updated accordingly.
+ *
+ * These values are used by the PCI configuration space,
+ * MP Tables.  TODO: Make ACPI use these values too.
+ *
+ * The Persimmon PCI INTA/B/C/D pins are connected to
+ * FCH pins INTE/F/G/H on the schematic so these need
+ * to be routed as well.
