61 * . CPU itself - 8 sources
62 * . i8259 - 16 sources
63 * . vrc5476 - 16 sources
64 *
65 * They connected as follows:
66 * all vrc5476 interrupts are routed to cpu IP2 (by software setting)
67 * all i2869 are routed to INTC in vrc5476 (by hardware connection)
68 *
69 * All VRC5476 PCI interrupts are level-triggered (no ack needed).
70 * All PCI irq but INTC are active low.
