Arjan van de Ven 62322d2554 [PATCH] make more file_operation structs static
Mark the static struct file_operations in drivers/char as const.  Making
them const prevents accidental bugs, and moves them to the .rodata section
so that they no longer do any false sharing; in addition with the proper
debug option they are then protected against corruption..

Temporary remove support for ICH6 + ICH7. In these newer TCO's
the watchdog timer has changed: the TCO_TMR register is not at

Calin A. Culianu eed6565f70 [PATCH] Watchdog: Winsystems EPX-C3 SBC
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.

Marcelo Tosatti fb64c2446b [PATCH] ppc32: m8xx watchdog update
This updates m8xx_wdt as follows:

1) Remove now obsolete fpos check in the write() function. The driver is
currently non functional due to this bug.

2) Use in/out macros for register access.

3) Allows m8xx_wdt to use a kernel timer instead of the builtin RTC/PIT
for keep-alive trigger (which is responsible for servicing the watchdog
until an userspace application takes over). For instance Cyclades PRxK
boards (MPC 855T based) have a non-functional internal RTC/PIT unit.
Behaviour for boards with RTC/PIT is unchaged.

4) The last change required moving the RTCSC register setting code
to a weak function which can be overriden by board specific files.
Otherwise the timer init code trashes the register making it impossible
for m8xx_wdt to detect the situation.
