SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

cyclic: Integrate cyclic infrastructure into WATCHDOG_RESET This patch integrates the main function responsible for calling all registered cyclic functions cyclic_run() into the common WATCHDOG_RESET macro. This guarantees that cyclic_run() is executed very often, which is necessary for the cyclic functions to get scheduled and executed at their configured periods. If CONFIG_WATCHDOG is not enabled, only cyclic_run() without calling watchdog_reset(). This guarantees that the cyclic functionality does not rely on CONFIG_WATCHDOG being enabled.

watchdog.h: Move hw_watchdog_init prototype to end, guard In commit abbab70 we added a prototype for hw_watchdog_init, in a Freescale i.MX watchdog driver. We did not however guard it with an __ASSEMBLY__ check and broke some platforms. Move this to the end of the file with other prototypes and guard it. Signed-off-by: Tom Rini <trini@ti.com>
