59 * Interrupt Controller Handling
60 *
61 * The interrupt controller handles interrupts for most on board interrupts,
62 * apart from PCI interrupts. For example on SBC610:
63 *
64 * 17:31 RO Reserved
65 * 16 RO PCI Express Doorbell 3 Status
66 * 15 RO PCI Express Doorbell 2 Status
67 * 14 RO PCI Express Doorbell 1 Status
68 * 13 RO PCI Express Doorbell 0 Status
69 * 12 RO Real Time Clock Interrupt Status
70 * 11 RO Temperature Interrupt Status
71 * 10 RO Temperature Critical Interrupt Status
72 * 9 RO Ethernet PHY1 Interrupt Status
73 * 8 RO Ethernet PHY3 Interrupt Status
74 * 7 RO PEX8548 Interrupt Status
75 * 6 RO Reserved
76 * 5 RO Watchdog 0 Interrupt Status
77 * 4 RO Watchdog 1 Interrupt Status
78 * 3 RO AXIS Message FIFO A Interrupt Status
79 * 2 RO AXIS Message FIFO B Interrupt Status
80 * 1 RO AXIS Message FIFO C Interrupt Status
81 * 0 RO AXIS Message FIFO D Interrupt Status
82 *
83 * Interrupts can be forwarded to one of two output lines. Nothing
84 * clever is done, so if the masks are incorrectly set, a single input
85 * interrupt could generate interrupts on both output lines!
86 *
87 * The dual lines are there to allow the chained interrupts to be easily
88 * passed into two different cores. We currently do not use this functionality
89 * in this driver.
90 *
91 * Controller can also be configured to generate Machine checks (MCP), again on
92 * two lines, to be attached to two different cores. It is suggested that these
93 * should be masked out.
