Introducing A bootloader timeout

[Abdul-Origo]

I am using SamD21 in weather Stations but due to ESD and Electrostatics, the bootloader mode gets kicked in. I was wondering how we can introduce a timeout to bootloader so after sometime it exits the bootloader automatically ( Lets say 5 minutes). Any help will be appreciated. I can compensate for the time if someone kind enough can have a look at it.
