+ * Chip contains built-in ELA with LCU (=Logic Capture Unit), that allows to
+ * collect profiling info. Collected data is aggregated via set of %cl_nlev
+ * elements, and saved inside special dump buffer (described by %cl_coredump)
+ * and fed to the userspace via DEV_COREDUMP subsystem.
+ *
+ * This layer is mandatory since it allows to set properly initial and
+ * post-recovery configuration.
