/*************************************************************************
* Exception Vector Table
*
* This could have gone in the cpu soure tree, but the whole point of
* Nios is customization -- and polluting the cpu source tree with
* board-specific ifdef's really defeats the purpose, no? With this in
* the board-specific tree, each board has the freedom to organize
* vectors/traps, etc anyway it wants. The init code copies this table
* to the proper location.
*
* Each board can do what it likes here. But there are four "standard"
* handlers availble:
*
* _cwp_lolimit -Handles register window underflows.
* _cwp_hilimit -Handles register window overflows.
* _timebase_int -Increments the timebase.
* _def_xhandler -Default exception handler.
*
* _timebase_int handles a Nios Timer interrupt and increments the
* timestamp used for the get_timer(), reset_timer(), etc. routines. It
* expects the timer to be configured like the standard-32 low priority
* timer.
*
* _def_xhandler dispatches exceptions/traps via the external_interrupt()
* routine. This lets you use the irq_install_handler() and handle your
* interrupts/traps with code written in C.
