tsk tsk pay attention 007 - the A10 CPU Card's done already! the GRB
files have been sent to the printers by wits-tech so we should have
them back in about a week.
but... arghh, yes i think we'll be able to get away with it. argh.
just specify the top 4 GPIOs as "reserved" for now. i was just
concerned about reducing the amount of GPIO
but, i think, because the plans are to use an embedded controller
(e.g. STM32F) that extends GPIO where it's more/most appropriate
