The current behavior of the start_if.act is resetting to the bootloader and assuming the bootloader will jump to the interface firmware, without doing anything specific. On certain targets (like Kinetis), the RST signal may be held down by the target due to buggy program being downloaded to the target, causing the probe enters bootloader mode in such condition. This patch adds another settings entry which will be set by the MSD command, and will temporarily make the bootloader ignoring the state of the RST pin, force starting the interface firmware.
