At the moment, Linux+Software is running on the SABRE board. The software in use accesses many peripheral interfaces. The SABRE pin mux differs quite a lot from the final pin mux setup that will be used for our custom hardware.
What happens if I change the pin configuration of the MX7? Especially, what happens to interfaces that are already used by the current software but will be mapped to different pins?
As the Signal/Data flow could be described as
Software <-> HW Interface <-> pin mux <-> pin
changing the pin configuration should only affect 'pin mux <-> pin'. In this case, no software/Linux adjustments should be necessary?
How does the MX7 learn about its new pin configuration?
