I'll add more documentation about the external system for more clarity [1]. Basically, Linux runs on the Cortex-A35. The External system is a Cortex-M core. The Cortex-A35 can not access the memory of the Cortex-M. It can only control Cortex-M core using the reset control and status registers mapped in the memory space of the Cortex-A35. I'll make sure this explanation is added to the binding and commit log for more clarity. Thanks for the suggestion regarding supporting multiple instances of the External system. I will send a new version shortly addressing all comments. [1]: paragraph 2.3, https://developer.arm.com/documentation/dai0550/D/?lang=en Kind regards Abdellatif
