The new Atmel AT91SAM9261 and AT91SAM9260 processors use a different
internal watchdog peripheral. This watchdog driver is therefore
AT91RM9200-specific.
This patch renames at91_wdt.c to at91rm9200_wdt.c, and changes the name
of the configuration option.

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.

In a project for my company I've needed to use the watchdog device in a
PCM-5335 SBC from AAEON. The watchdog timer is from a Winbond's SuperIO
chip, the W83977F.
I've made this driver based on two others already on the kernel tree,
the w83877f_wdt and the wdt977.

I wrote earlier to the list[1] asking for a driver for the watchdog
included in the 6300ESB chipset. I got a 2.4 driver via private email
from Ross Biro which I've changed into what I hope resembles a 2.6
driver (which was done by looking a lot at the watchdog drivers
already in the 2.6 tree).
I've attached the result, and I'm hoping to get some feedback on the
coding as a first step. I can't actually test it on the hardware
right now as I won't have physical access until April. So my own tests
have been limited to "compiles-without-warnings" and
"can-be-insmodded-in-other-machine-without-oops".

PowerPC 40x and Book-E processors support a watchdog timer at the processor
core level. The timer has implementation dependent timeout frequencies
that can be configured by software.
One the first Watchdog timeout we get a critical exception. It is left to
board specific code to determine what should happen at this point. If
nothing is done and another timeout period expires the processor may
attempt to reset the machine.
Command line parameters:
wdt=0 : disable watchdog (default)
wdt=1 : enable watchdog
wdt_period=N : N sets the value of the Watchdog Timer Period.
The Watchdog Timer Period meaning is implementation specific. Check
User Manual for the processor for more details.
This patch is based off of work done by Takeharu Kato.

Add a watchdog using the RTAS OS surveillance service. This is
provided as a simpler alternative to rtasd. The added value
is that it works with standard watchdog client programs and
can therefore also do user space monitoring.
On BPA, rtasd is not really useful because the hardware does
not have much to report with event-scan.
The driver should also work on other platforms that support
the OS surveillance rtas calls.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
