watchdog: Implement generic watchdog_reset() version This patch tries to implement a generic watchdog_reset() function that can be used by all boards that want to service the watchdog device in U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG. Without this approach, new boards or platforms needed to implement a board specific version of this functionality, mostly copy'ing the same code over and over again into their board or platforms code base. With this new generic function, the scattered other functions are now removed to be replaced by the generic one. The new version also enables the configuration of the watchdog timeout via the DT "timeout-sec" property (if enabled via CONFIG_OF_CONTROL). This patch also adds a new flag to the GD flags, to flag that the watchdog is ready to use and adds the pointer to the watchdog device to the GD. This enables us to remove the global "watchdog_dev" variable, which was prone to cause problems because of its potentially very early use in watchdog_reset(), even before the BSS is cleared.

board_f: fix noncached reservation calculation The current code in reserve_noncached() has two issues: 1) The first update of gd->start_addr_sp always rounds down to a section start. However, the equivalent calculation in cache.c:noncached_init() always first rounds up to a section start, then subtracts a section size. These two calculations differ if the initial value is already rounded to section alignment. 2) The second update of gd->start_addr_sp subtracts exactly CONFIG_SYS_NONCACHED_MEMORY, whereas the equivalent calculation in cache.c:noncached_init() rounds the noncached size up to section alignment before subtracting it. The two calculations differ if the noncached region size is not a multiple of the MMU section size. In practice, one/both of those issues causes a practical problem on Jetson TX1; U-Boot triggers a synchronous abort during initialization, likely due to overlapping use of some memory region. This change fixes both these issues by duplicating the exact calculations from noncached_init() into reserve_noncached(). However, this fix assumes that gd->start_addr_sp on entry to reserve_noncached() exactly matches mem_malloc_start on entry to noncached_init(). I haven't traced the code to see whether it absolutely guarantees this in all (or indeed any!) cases. Consequently, I added some comments in the hope that this condition will continue to be true.
