Hi,
As part of the ongoing rebase effort, the following configuration
options need to be reviewed.
As a reminder, the ARK configuration flow involves moving unreviewed
configuration options from the pending directory to the ark directory.
In the diff below, options are removed from the pending directory and
added to the ark hierarchy. The final options that need to be ACKed
are the files that are being added to the ark hierarchy.
If the value for a file that is added should be changed, please reply
with a better option.
CONFIG_CORESIGHT_TRBE:
This driver provides support for percpu Trace Buffer Extension (TRBE).
 TRBE always needs to be used along with it's corresponding percpu ETE
 component. ETE generates trace data which is then captured with TRBE.
 Unlike traditional sink devices, TRBE is a CPU feature accessible via
 system registers. But it's explicit dependency with trace unit (ETE)
 requires it to be plugged in as a coresight sink device.
To compile this driver as a module, choose M here: the module will be
 called coresight-trbe.
 Symbol: CORESIGHT_TRBE [=n]
 Type  : tristate
 Defined at drivers/hwtracing/coresight/Kconfig:177
   Prompt: Trace Buffer Extension (TRBE) driver
   Depends on: CORESIGHT [=m] && ARM64 [=y] && CORESIGHT_SOURCE_ETM4X [=m]
   Location:
     -> Kernel hacking
       -> arm64 Debugging
         -> CoreSight Tracing Support (CORESIGHT [=m])
