Might be simpler to either (1) add a dummy module with I2C functions that always return error/false, or (2) dedicate two I/O pins on the board to I2C since many use cases will want it anyway.

I am open to either option. Note that if I did go with (2), dedicating two I/O pins, I would need to update zynq-rs for this as well. What do you deem the better option?

Another zynq-rs update is not a problem, but if it's too contrived, you may go with dummies for now and add I2C support later.
