8.2. Component Interfaces
The SDM provides commands which are accessed by ATF (Arm Trusted Firmware). ATF exports the functionality through an SMC (Secure Monitor Call) handler for the rest of HPS software to use.
You can access the RSU functionality through U-Boot. The SMC handler is used by U-Boot to implement the RSU functionality.
You can also access the RSU services through LIBRSU. In this case the SMC handler is used by the Linux* kernel drivers which then expose the functionality to LIBRSU which then is used by Linux* applications in general, and RSU Client application in particular.
The horizontal dotted lines in the above diagrams show interfaces between components. The SDM firmware, U-Boot and LIBRSU access the SDM Flash, so an interface is shown there too.
