[PATCH 07/13] watchdog: kvx: do not disable watchdog on probe

[Jules Maselbas <jmaselbas@kalray.eu>]

From: Louis Morhet <lmorhet@kalray.eu>

As the watchdog may be set by a lower stage in the boot chain, and for
a good reason (precisely to ensure reliable update when something
unexpected happens during the boot chain), it is a bad idea to always
disable it during probe.

We should either have a mechanism to refresh it on a regular basis in
barebox itself and set it to something bigger for Linux, or handle it
transparently and let the previous stage set the global watchdog up to
Linux. This patch assumes for now the latter.
