	  spcom driver allows loading Secure Processor Applications and

	  sending messages to Secure Processor Applications.

	  spcom provides interface to both user space app and kernel driver.

	  It is using glink as the transport layer, which provides multiple

	  logical channels over single physical channel.

	  The physical layer is based on shared memory and interrupts.

	  spcom provides clients/server API, although currently only one client

	  or server is allowed per logical channel.
