We only use it on ZYNQ and Microblaze though. And people have complained in the past about symbols that are viable on their platform, but are not relevant for their platform. And to use the core on a different FPGA platform will most likely require changes to the core, unless the other FPGA also has a PL330 DMA interface. So I'd prefer to only make it avaiable on ZYNQ and Microblaze right now.
Is it really restricted to PL330 at the hardware level? I don't recall anything too fancy in the datasheet there.
Yes, it is using the PL330 peripheral request interface. See http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0424a/index.h... and https://github.com/analogdevicesinc/fpgahdl_xilinx/blob/master/cf_lib/edk/pc...
