Remote Debug as a platform resource


I am trying to do something different and thought the expertise of the community may be able to give me some pointers. I understand that it’s possible to provide remote debug functionality using the SLD Hub controller in any Altera SoC. But I wanted to see if I can provide this featureas a platform resource when my processor is a power pc sitting outside the Altera device. We would still run Linux.

I see that Altera has something called JTAG Tap Controller. I am wondering if the sources for those are available and/or deprecated.

Any suggestions, pointers, etc. to achieve this goal will be great.

Thank you.
Best regards,
