This example has no support for legacy PIC routing. For PIC routing you would need  to alter rest of the fields in the _PRT package and also crete PIRQA-PIRQD special devices.

Rest of the file contains just some legacy devices to make certain OS instatallers happy.
The described above uses static IRQ assignments. Some chipsets like MPC55/CK804 have a configuration register
which indicates what APIC pin are routed to what interrupt. Those typically use dynamic IRQ routing which provides
a _CRS and _SRS methods to set such registers. For now, those registers are filled in MP-Table setup of each MCP55/CK804 board. All you need is to have static wiring like the MP-Table has.
