+Subject: [PATCH 1/8] lite: Add config option to enable benchmark_model
+
+It's handy to have an option to enable the benchmark_model tool
+so that it can be built and installed using the all target which
+is preferable in some cases when packaging tensorflow-lite.

+Subject: [PATCH 3/8] feat(tflite): Add dynamic OpenCL library loading support
+
+Use pkg-config to detect OpenCL installation and set library name based on
+OpenCL version. Pass library name as compile-time definition to OpenCL wrapper
+and modify wrapper to use configured name instead of hardcoded defaults.
+This fixes OpenCL library loading issues on systems with non-standard
+installations and various Linux distributions.
