Arria 10 with separate hardened DDR controller for PL and HPS

I have come up with a set of requirements for the memory and I realized my PL memory needs are critical. I understand there is a x72 DDR4 hardened PHY+Controller+MPFE in the Arria10 and I'd like t...

Is there linux support to access FPGA DDR?

Are you saying you would like to use HPS to access the FPGA DDR memory over the H2F bridge? Right now I don't think the HPS can support 2 memory controller instances (one in its own HPS DDR and the other FPGA memory) - besides, it would be quite inefficient to do it over the H2F bridge. I believe letting the FPGA access the HPS DDR over the F2S bridge is a better alternative.
