arm64: errata: Enable TRBE workaround for write to out-of-range address (2021-10-25 12:06:02 -0600)
----------------------------------------------------------------
Coresight changes for v5.16
- A new option to make coresight cpu-debug capabilities available as early as possible in the kernel boot process.
- Make trace sessions more enduring by coping with scenarios where events are scheduled on CPUs that can't reach the selected sink.
- A set of improvement to make the TMC-ETR driver more efficient.
- Enhancements to the TRBE driver to correct several errata.
- An enhancement to make the AXI burts size configurable for TMC devices that can't work with the default value.
- A fix in the CTI module to use the correct device when calling pm_runtime_put()
- The addition of the Kryo-5xx device to the list of support ETMs.
