Securing JTAG on i.mx28

I'm using i.mx283 (i.MX283 Processors|High-Performance|NXP )

Couldn't find any documents on how to disable/partially disable JTAG port.  Is this application note valid for i.mx28?  


Is it possible to disable JTAG memory access(keeping boundary scan enabled) ?

Is it possible to do this without any manufacturing tools, directly from the Linux running on the processor?
