Late to the conversation, so i might be asking questions already
asked...

So the PLD has restrictions? You have a collection of GPOs and a
collection of GPIs? You don't have an GPIOs?

Do these names have any real significant? Are you really forced to
connect the SFP cage in this dedicated manor? Is there any reason why
i cannot use a GPO to control an LED? A GPI for a button?
