+description:
+ TMEL SS provides different kinds of services like secureboot, remote image authentication,
+ key management, crypto, OEM provisioning etc. This patch adds support for remote image
+ authentication. Support for rest of the services can be added.
+
+ The QMP mailbox is the primary means of communication between TMEL SS and other subsystem on
+ the SoC. A dedicated pair of inbound and outbound mailboxes is implemented for each
+ subsystem/external execution environment which needs to communicate with TMEL for security
+ services. The inbound mailboxes are used to send IPC requests to TMEL, which are then processed
