1 /*
2 * Cisco 7200 (Predator) simulation platform.
3 * Copyright (c) 2005,2006 Christophe Fillot (cf@utc.fr)
4 *
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
