This is a 2.6 patch that adds support for the watchdog timer built into the EPX-C3 single board computer manufactured by Winsystems, Inc. Driver details: This is for x86 only. This watchdog is pretty basic and simple. It is only configurable via jumpers on the SBC, and it only has either a 1.5s or 200s interval. The watchdog can either be auto-configured to start as soon as the machine powers up (bad idea for the 1.5s interval!) or it can be enabled and disabled by writing to io port 0x1ee. Petting the watchdog involves writing any value to io port 0x1ef. The only unfortunate thing about this watchdog (and it is not at all uncommmon in watchdogs that linux supports) is that it is not a PCI or ISA-PNP device and as such it isn't at all probeable. Either the watchdog exists as 2 bytes at 0x1ee, or it doesn't. Thus, using this driver on a machine that doesn't have that watchdog can potentially hang/crash the system, etc. So only use this driver if you in fact are on a Winsystems EPX-C3 SBC. Anyway this driver fits into the already-existing watchdog framework quite nicely and I already tested it on my EPX-C3 and it works like a charm. Signed-off-by: Calin A.

# 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.
