Now I understand. You say that the SRAM address space is made available
to the pxa user through your FPGA driver. Can you change that driver to
make it export the SDRAM contents as a block device file (call it
/dev/fpga-sdram)? If you can do that, then g-file-storage will be able to
use the file as the backing storage.
I'm not shure about that. I'm not that familiar with block device drivers. If someone have some example I'll appreciatte it. This idea looks like the most elegant.
If the driver you had previously written was actually a user-space application, you might consider using FUSE to provide a "filesystem" from a userspace deamon.
This will probably have some overhead, but it might not be noticeable in the end.
