Two variables of the bootloader are persistent: - __stack_chk_guard is used by interrupt handlers - system_millis is used by timer interrupt and service routines Note that currently __stack_chk_guard is shared between unprivileged firmware and bootloader. If we get more variables later it may make sense to make a section for this.
