+/*************************************************************************
+ * 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.

+4. BOOT PROCESS
+---------------
+
+4.1 Boot process over GERMS
+---------------------------
+When the NIOS CPU catch a reset signal it will begin to be running
+code from CFG_NIOS_CPU_RST_VECT. Normally at this place it will
+find the GERMS monitor. That's the case for the generic NIOS CPU
+configuration "standard_32". When the GERMS monitor starts running,
+it performs important system initializations and then looks for
+executable code in flash, using the following steps:
+
+ 1. Examining the two bytes at CFG_NIOS_CPU_FLASH_BASE + 0x04000C.
+ 2. Examining the button 0 on the PIO CFG_NIOS_CPU_BUTTON_PIO.
+ 3. If the button is not pressed and the two bytes contain 'N'
+ and 'i', the monitor executes a CALL to location
+ CFG_NIOS_CPU_FLASH_BASE + 0x040000.
+ 4. If the code is not executed in step 3 or the code returns,
+ then prints an 8-digit version number to STDOUT and waits for
+ user commands from STDIN.
+
+In normal case, for "standard_32", STDIN and STDOUT are the first
+serial port.
+
+4.2 Return to GERMS command line
+--------------------------------
+During the boot process, the GERMS monitor checks for the existence
+of application software in flash memory. If found, the processor
+immediately executes the code. To return program execution to the
+GERMS monitor (that is, avoid running code stored in flash memory):
+
+ 1. Hold down CFG_NIOS_CPU_BUTTON_PIO, button number 0.
+ 2. Press then release the CPU reset button.
+ 3. Release CFG_NIOS_CPU_BUTTON_PIO, button number 0.
