Zephyr Support for Heterogeneous SoCs
summary
Enables Zephyr on AM243x EVM by adding board support, device trees, Kconfig entries, linker script and device drivers, using Zephyr’s DT-to-header generation and CMake; solves MPU region issues by placing SRAM in an mpu_config array instead of DT attributes to allow user mode; finds a critical MCUBoot limitation — it does not handle multi-core heterogeneous boot, so TI’s RTOS bootloader is used; surfaces need for centralized clock/power/resource domain management and occasional vendor-specific driver APIs and autogenerated syscalls.
