Nothing too dificult there - IO is currently defined as 24 bits in at most, half a dozen places. Mapping the internal connections to physical pins would be the bulk of any work. > I think this is a case of modifying the hostmot4 configuration, and then > updating the hal_m5i20.c driver to suit the new fpga configuration. Applying a couple of new constraints in the driver would expose the extra IO, again, nothing too taxing there. The worst part is the notion that firmware *has* to be embedded in the module or some untrusted user space utility is required to preload the fpga - The kernel already provides a mechanism for firmware loading without resorting to NIMBY code. A few minutes with a text editor would see the changes you need in place. To rework the driver so that it does the right thing wrt firmware would take a little longer.
