SPM: Introduce Secure Partition Manager
A Secure Partition is a software execution environment instantiated in S-EL0 that can be used to implement simple management and security services. Since S-EL0 is an unprivileged exception level, a Secure Partition relies on privileged firmware e.g. ARM Trusted Firmware to be granted access to system and processor resources. Essentially, it is a software sandbox that runs under the control of privileged software in the Secure World and accesses the following system resources: - Memory and device regions in the system address map. - PE system registers. - A range of asynchronous exceptions e.g. interrupts. - A range of synchronous exceptions e.g. SMC function identifiers. A Secure Partition enables privileged firmware to implement only the absolutely essential secure services in EL3 and instantiate the rest in a partition. Since the partition executes in S-EL0, its implementation cannot be overly complex. The component in ARM Trusted Firmware responsible for managing a Secure Partition is called the Secure Partition Manager (SPM). The SPM is responsible for the following: - Validating and allocating resources requested by a Secure Partition. - Implementing a well defined interface that is used for initialising a Secure Partition. - Implementing a well defined interface that is used by the normal world and other secure services for accessing the services exported by a Secure Partition. - Implementing a well defined interface that is used by a Secure Partition to fulfil service requests. - Instantiating the software execution environment required by a Secure Partition to fulfil a service request.
