Mingarelli, Thomas authored
This patch is being created to use the UEFI bits in the type 219 SMBIOS record in order to decide whether or not to execute BIOS code. This is a better solution than to depend on the iCRU bit since not all future servers will use iCRU. Signed-off-by:

In watchdog_ping(), 'start' is called automatically when 'ping' function call is not configured. Softdog driver has same handling in both cases - start and ping, so 'ping' OPS can be removed. Signed-off-by:

The bits in BRIDGE_CAUSE are documented as RW0C - read, write 0 to clear. If we read the register, mask off the watchdog bit, and write it back, we're actually clearing every interrupt which wasn't pending at the time we read the register - and that is racy. Fix this to only write ~WATCHDOG_BIT to the register, which means we write as zero only the watchdog bit. Signed-off-by:

The watchdog infrastructure in Dove is no different from that in Orion5x or Kirkwood, so let's enable it for Dove. The only things missing are a few register settings in Dove's bridge-regs.h. Rather than duplicating the same register bit masks for the RSTOUTn_MASK and BRIDGE_CAUSE registers, move the definitions into the watchdog driver itself. Signed-off-by:

Interrupt request doesn't use the right API: The TWD watchdog uses a per-cpu interrupt (usually interrupt #30), and the GIC configuration should flag it as such. With this setup, request_irq() should fail, and the right API is request_percpu_irq(), together with enable_percpu_irq()/disable_percpu_irq(). Nothing ensures the userspace ioctl() will end-up kicking the watchdog on the right CPU. There are no users of this driver since a long time and it makes more sense to get rid of it as nobody is looking to fix it. In case somebody wakes up after this has been removed and needs it, please revert this driver and pick these updates (These were never pushed to mainline): http://comments.gmane.org/gmane.linux.ports.arm.kernel/245998Signed-off-by:

A watchdog device may be stopped from userspace using WDIOC_SETOPTIONS ioctl and flag WDIOS_DISABLECARD. If the device is closed after this operation, watchdog_release() is called and status bits checked for stopping it. Besides, if the device has not been unregistered a critical message "watchdog did not stop!" is printed, although the ioctl may have successfully stopped it already. Without the patch a user application sample code like this will successfully stop the watchdog, but the kernel will output the message "watchdog did not stop!": wd_fd = open("/dev/watchdog", O_RDWR); flags = WDIOS_DISABLECARD; ioctl(wd_fd, WDIOC_SETOPTIONS, &flags); close(wd_fd); Signed-off-by:Hector Palacios <hector.palacios@digi.com> Reviewed-by:

This reverts commit d2aae847. It is completely and utterly broken. Module install should not build any files, and adding broken dependencies to "help" it build files is complete and utter sh*t. The kernel should not be built by root, and "make install" and "make module_install" (that for obvious reasons need to be run as root) absolutely must not build any files. They should only ever copy the already-built files over. So having dependencies for the install targets is wrong, wrong, wrong. If you try to install a kernel without building it first, you *should* get errors. The build system shouldn't try to help root build the files. Signed-off-by:
