Any built-in Linux methods for AXI-burst type devices?

I need to communicate with an FPGA device based on an AXI-burst interface. What are the ways to access such a device through Linux without involving a DMA? Burst is an intrinsic property of the AXI standard, which should typically be triggered automatically when large amounts of data are being transferred. And the bigger problem is the FPGA is designed so as to respond only to burst type requests over the AXI bus. So this causes serious issues on Linux when the application tries sequential copy.
P.S. I have already tried memcpy and it doesn't work.
