^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)   Arm Embedded Trace Extension(ETE) is a per CPU trace component that
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16)   allows tracing the CPU execution. It overlaps with the CoreSight ETMv4
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17)   architecture and has extended support for future architecture changes.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18)   The trace generated by the ETE could be stored via legacy CoreSight
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19)   components (e.g, TMC-ETR) or other means (e.g, using a per CPU buffer
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20)   Arm Trace Buffer Extension (TRBE)). Since the ETE can be connected to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21)   legacy CoreSight components, a node must be listed per instance, along
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22)   with any optional connection graph as per the coresight bindings.
