Is AM437x SMP SOC ? Is TWD on AM437x works in low
power states ?
Probably I haven't followed the recent updates, but does
the TWD supports C3STOP on UP systems ? The broadcast
code was SMP only in past, and TWD use to die in
low power state on past OMAP SOCs.

If either of these are still the issue then
TWD shouldn't be used.
