msm: Secure Channel Manager (SCM) support SCM is the protocol used to communicate between the secure and non-secure code executing on the applications processor. The non-secure side uses a physically contiguous buffer to pass information to the secure side; where the buffer conforms to a format that is agreed upon by both sides. The use of a buffer allows multiple pending requests to be in flight on the secure side. It also benefits use cases where the command or response buffer contains large chunks of data.
