 # 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.
