  arm64: errata: Enable TRBE workaround for write to out-of-range address (2021-10-27 11:46:06 -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.

Much better, thanks!

Now pulled and pushed out.
