Agilex 5 fpga2sdram firewall

Is there a fpga2sdram firewall in the Agilex 5?

I can see that there is one in the Agilex 7 which handles access to SDRAM

However, in the register map for the A5 - there is only mention of firewalls in the OCRAM section.

I am asking as I am trying to transfer data from OCM to SDRAM on the Agilex 5, and am finding that I can do so using U-Boot scripting but not with Linux scripting.

Many thanks!
