The Corstone-1000 IoT Reference Design Platform [A] supports up to two External Systems processors. This patchset allows to control these processors through the remoteproc subsystem. The Corstone-1000 implements the SSE-710 subsystem [B] which defines the MMIO-mapped reset registers (EXT_SYS*) used for controlling the External Systems [C]. This patchset provides the following: - Device tree bindings for the SSE-710 subsystem with syscon support - Device tree bindings for the SSE-710 External System - Corstone-1000 External System, syscon and MHUs device tree nodes - Arm MHUv2 Mailbox [F] device tree nodes for Corstone-1000 - Corstone-1000 remoteproc driver with regmap support For more details, please see the SSE-710 External System Remote Processor bindings [D] and the SSE-710 Host Base System Control bindings [E].
