+Advanced Extended IRQ model
+===========================
+
+In this model, IPI (Inter-Processor Interrupt) and CPU Local Timer interrupt go
+to CPUINTC directly, CPU UARTS interrupts go to LIOINTC, MSI interrupts go to AVEC,
+and then go to CPUINTC, Other devices interrupts go to PCH-PIC/PCH-LPC and gathered
+by EIOINTC, and then go to CPUINTC directly::
