I have a need of several more GPIOs and not enough pins.
My design calls for the booting to be done via parallel NOR Flash, however after the boot phase I have no need for the flash and will not be using it at all. And I have a shortage in GPIOs.
My idea is that after booting is complete, to re-configure some of the pins used as SMC addresses as GPIOs.
Is it possible to reconfigure pins to change functionality after booting?
