CoreSight base addr and DAP port number

Note: This was originally posted on 28th March 2013 at http://forums.arm.com

hi, experts:
I am using a JTAG debugger.
It needs to set every cpu core's coresight base in the config page.
So, i have 2 questions:
1. no registers to record every cpu core's coresight base addr?
2. I also need to set DAP port number : 0/1
So, why need to set DAP port number?
I think it should be only 1 DAP port in ARM SOC.

best wishes,
