Hi,
Recently, I learned about Nailgun [1] – leak information by snooping across privilege boundaries with the help of CoreSight. The proof of concept uses Raspberry Pi3 (uses Cortex A-53 CPUs) platform to demonstrate the exploit.
Has anyone reviewed this attack and does it affect other Arm v8 CPUs too? Do we have support in TF-A to disable CoreSight to mitigate against such attacks? Are there any other mitigations against this attack?

Thanks for the pointers, Joanna.
