We had been told the following:
"The system reset (from our DS1819) reset generator is routed to both 
the processor and the flash devices #RP pin. ... the board does contain 
a hardware watchdog which can be enabled by loading R11 with a zero ohm 
resistor (location on bottomside by CF connector). You will then need to 
strobe CPU GPIO14."

We are using the ixp4xx_wdt.c watchdog in linux.  Can the folks at 
gateworks confirm if this watchdog will reset the flash or if we need to 
use a different one?
