Does the DEVARCH indicate that it is an ETMv4 ? (It should !) Please
could we enforce the UCI_ID check for these components ? The
moment you add CTI components to your board this could conflict with
them unless we check the UCI_ID for ETMv4.
Yes I got these IDs through devarch and it does indicate that it is
ETMv4.2.

I will add the UCI_ID as you suggested in next version.
If you do have access to the Kryo 385 variants, please fix
them as well.
Sure, will do.
Thanks,
