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.
