2009-09-18[WATCHDOG] ar7_wdt: convert to become a platform driverFlorian Fainelli
This patch converts the ar7_wdt driver to become a platform driver. The AR7 SoC specific identification and base register calculation is performed by the board code, therefore we no longer need to have access to ar7_chip_id. We also remove the reboot notifier code to use the platform shutdown method as Wim suggested. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2009-09-18[WATCHDOG] fix book E watchdog to take WDIOC_SETTIMEOUT arg in secondsChris Friesen
The WDIOC_SETTIMEOUT argument is supposed to be a "seconds" value. However, the book E wdt currently treats it as a "period" which is interpreted in a board-specific way. This patch allows the user to pass in a "seconds" value and the driver will set the smallest timeout that is at least as large as specified by the user. It's been tested on e500 hardware and works as expected. The patch only modifies the CONFIG_FSL_BOOKE case, the CONFIG_4xx case is left unmodified as I don't have any hardware to test it on.

2009-06-18[WATCHDOG] iTCO_wdt: Fix ICH7+ reboot issue.Wim Van Sebroeck
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.

Symbols like SOFT_RESET are way too generic to be exported at large. To avoid this, let's move the mbus bridge register defines into a separate file and include it where needed. This affects mach-kirkwood, 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. This fixes compilation problem with mpt2sas on the above listed platforms.
