Yes both ways should be doable.

Well I doubt that anybody wants to keep it permanently enabled
because of the power consumption and blocking of PM states, so
an additional cmdline might make sense.
It would be nice to have it most of the time built-in but disable
itself unless something debug is specified in the cmdline.
Maybe the JTAG driver can detect when the cable is connected?
Or maybe that would be only when there's clock coming over
JTAG?

Tony
