[v2] coresight: trbe: Update existing errata for Cortex-X2

[PATCH V2 0/2] coresight: trbe: Update existing errata for Cortex-X2

Posted by Anshuman Khandual 4 years, 5 months ago

Errata ARM64_ERRATUM_[2119858|2224489] also affect some Cortex-X2 ranges as
well. This series updates the errata definition and detection as required.
This series applies on v5.17-rc1.

Relevant identification document can be found here.
