+-  Memory Tagging Extension feature has few variants but not all of them require
+   enablement from EL3 to be used at lower EL. e.g. Memory tagging only at
+   EL0(MTE) does not require EL3 configuration however memory tagging at
+   EL2/EL1 (MTE2) does require EL3 enablement and we need to set this option
+   ``ENABLE_FEAT_MTE2`` to 1. This option defaults to 0.
