Remote Processor Framework in Zephyr RTOS
summary
Proposes a Remote Processor subsystem for Zephyr RTOS and demonstrates a proof‑of‑concept on TI AM62x with Cortex‑A53 as host and M4 as client; implements host APIs for prepare/load/start/stop/unprepare, an ELF loader reusing lxt helpers, and device address to virtual address mapping for cross‑architecture firmware placement; uses System Controller messaging to power/reset domains and loads firmware via U‑Boot/network; outcome boots Zephyr on A53 and a working M4 console concurrently, showing the approach works.
