Florian Fainelli c5e7f5a38a [WATCHDOG] ar7_wdt: fix path to ar7-specific headers
AR7 is currently being resubmitted for mainline inclusion
and we changed the path to the ar7-specific headers
from ar7 to mach-ar7 to reflect the other MIPS-based
boards header hierarchy. This patch will avoid any future
compilation failure due to missing headers.

This patch contains two fixes:

1)In omap_wdt_probe() the watchdog is reset and disabled. This
requires register access and the clks needs to be enabled temporarily

2)In omap_wdt_open() the timer register needs to be reloaded
to trigger a new timer value (the default of 60s)

Tested on OMAP34xx platform (Zoom1)

Because the watchdog timeout is very short (about 2s), a soft timer is used
to increase the watchdog period.

Note : A patch for exporting the ssb_watchdog_timer_set will
be submitted on next linux-mips merge. Without this patch it can't

Wim Van Sebroeck 55e8ddecec [WATCHDOG] iTCO_wdt: Fix ICH7+ reboot issue.
Bugzilla: 9868 & 10195.
There seems to be a bug into the SMM code that handles TCO Timeout SMI.
Andriy Gapon found that the code on his DG33TL system does the following:
> The handler is quite simple - it tests value in TCO1_CNT against 0x800, i.e.
> checks TCO_TMR_HLT. If the bit is set the handler goes into an infinite loop,
> apparently to allow the second timeout and reboot. Otherwise it simply clears
> TIMEOUT bit in TCO1_STS and that's it.
> So the logic seems to be reversed, because it is hard to see how TIMEOUT can
> get set to 1 and SMI generated when TCO_TMR_HLT is set (other than a
> transitional effect).

The only trick we have is to bypass the SMM code by turning of the generation
of the SMI#. The trick can only be enabled by setting the vendorsupport module
parameter to 911. This trick doesn't work well on laptop's.

Note: this is a dirty hack. Please handle with care. The only real fix is that
the bug in the SMM bios code get's fixed.

To avoid this, let's move the mbus bridge register defines into a

mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all
share code in plat-orion which relies on those defines.

Some other defines have been moved to narrower scopes, or simply deleted
when they had no user.

Wim Van Sebroeck fc8a9d830f [WATCHDOG] i6300esb.c: Restructure initialization of the device
The i6300ESB watchdog should be stopped before userspace has access to the
watchdog. So fix this and restructure the initialization sequence into:
	* See if we have a i6300 device
	* make sure that we have valid module parameters
	* Initialize the device
	* register the /dev/watchdog device so that userspace has access

Wim Van Sebroeck 31838d9dac [WATCHDOG] i6300esb.c: Fix the GETSTATUS and GETBOOTSTATUS ioctls.
The WDIOC_GETSTATUS and WDIOC_GETBOOTSTATUS should return WDIOF_* flags
(and not counter values, ...)

Mark Nelson b6966b1be5 powerpc/wdrtas: Update wdrtas_get_interval to use rtas_data_buf
The buffer passed to the ibm,get-system-parameter RTAS call must be
in the RMA.  To ensure we pass an address in the RMA use rtas_data_buf
for the actual RTAS call and then copy the result to value.  We can't
just make it static because this can be compiled in as a module.

Also add the WDRTAS_SP_SPI_LEN so we don't litter '4' throughout the
function.

Jean Delvare e7a19c5624 dmi: Let dmi_walk() users pass private data
At the moment, dmi_walk() lacks flexibility, users can't pass data to
the callback function. Add a pointer for private data to make this
function more flexible.
