How can Linux read data using the f2sdram bus?

Hi,

I'm using the Cyclone V and the hps runs with Linux.

I want to transfer big data blocks from fpga to the hps and send them via Gbit-Ethernet.

The first thought was to transfer the data over the f2h-bridge and using the f2h device that is detected by Linux.

But the on second thought transferring data over the f2sdram-bus could be much faster?

So the fpga writes the data block on a defined base-address in the sdram.

But with Linux I can't specify the address on which i want to place my data-array or from which i want to read the data in the sdram.

So can I define a new device in my device tree so Linux detects that device and knows from which address to read?

And if so do i have to write a device driver or is there an existing Driver in the Linux Kernel for the f2sdram-bus?

Best regards,

Robert
