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. 

https://www.nxp.com/docs/en/application-note/AN4686.pdf  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?

 

Thanks,

- Abhijith
