5     * Generic Cisco 7200 routines and definitions (EEPROM,...).
6     *
7     * Notes on IRQs (see "show stack"):
8     *
9     * - triggering IRQ 3: we get indefinitely (for each slot):
10     * "Error: Unexpected NM Interrupt received from slot: 6"
11     *
12     * - triggering IRQ 4: GT64010 reg access: probably "DMA/Timer Interrupt"
13     *
14     * - triggering IRQ 6: we get (probably "OIR/Error Interrupt")
15     * %ERR-1-PERR: PCI bus parity error
16     * %ERR-1-SERR: PCI bus system/parity error
17     * %ERR-1-FATAL: Fatal error interrupt, No reloading
18     * err_stat=0x0, err_enable=0x0, mgmt_event=0xFFFFFFFF
