Are these all the wdts in main domain - do define and leave the other wdts
disabled as they are tightly coupled to other processors (and must be
enabled by the OS running on them), but defining them allows us to reuse
the definitions in OSes running on R5s (for instance) to reuse the same
device definitions.

Hello Nishanth,
Okay. I will add all the remaining ones & keep them disabled.
Thanks for the feedback.
