Off board memory

Hi all, this is my first time here.
I'm looking for help setting up a mapped drive that reflects the contents of external memory, which is located across a PCIe bus on another board, controlled by an FPGA. I have Xilinx's XDMA kernel module loaded and can access the memory through it. I was thinking my next step was to develop a block driver that interfaces with this module, and finally a file system module that would interface with the block driver. Then I could just mount a drive using that file system driver, and have access to the memory. Is this the right path? Or is something that cannot possibly happen? I'm new to Linux, so I'm hoping to get an experts opinion.
Thanks in advance,
Dave
