[ Upstream commit 31fac56577 ]
From CMN-650 onwards, some of the fields in the watchpoint config
registers moved subtly enough to easily overlook. Watchpoint events are
still only partially supported on newer IPs - which in itself deserves
noting - but were not intended to become any *less* functional than on
CMN-600.
