# Makefile for the WatchDog device drivers.

# Only one watchdog can succeed. We probe the ISA/PCI/USB based

# watchdog-cards first, then the architecture specific watchdog

# drivers and then the architecture independant "softdog" driver.

# This means that if your ISA/PCI/USB card isn't detected that

# you can fall back to an architecture specific driver and if

# that also fails then you can fall back to the software watchdog

# to give you some cover.
