Re: How to use PL330 in ZYNQ?

Some threads on the linux driver side of things for recent kernel versions:

The PL330 signalling is reasonably documented in the Zynq TRM. I think that info is derived from the PL330 doc at ARM itself.

Re: How to use PL330 in ZYNQ?

Not sure what you are asking. If you are asking about the PL330 microcode/opcodes, that is also covered in the PL330 TRM at ARM. The HTML version:
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0424a/index.html
and the PDF version:
