+description:
+  The BIST (Built-In Self Test) module is an IP block present in K3 devices
+  that support triggering of BIST tests, both PBIST (Memory BIST) and LBIST
+  (Logic BIST) on a core. Both tests are destructive in nature. At boot, BIST
+  is executed by hardware for the MCU domain automatically as part of HW POST.
