Enhancing OpenAMP: Making Linux and Zephyr Work Better Together
summary
Real problem: shared memory appears at different physical addresses and firmware ready signaling is inconsistent on NXP heterogeneous boards. The work implements address translation support inside Zephyr OpenAMP, adds a vendor-specific resource table format and exposes a Linux remoteproc handler to parse it, and lands the fixes upstream in both Zephyr and Linux. The actual build runs on NXP hardware, resolves mismatched mappings and optional firmware-ready waits, and is reported as merged and working.
