set of basic bash scripts to remove/insert SOF Linux kernel modules in the right order. This is typically used to avoid rebooting every time the SOF image or topology are updated - and detect leaks on remove.

sof_remove.sh: remove all SOF modules sof_insert.sh: probe SOF modules sof_bootone.sh: combination of remove/insert in one shot sof_bootloop.sh: boot loop to see if firmware boot is reliable over time

This can probably be enhanced to remove spurious "module is not currently loaded" logs.
