+	  Select this option to enable driver support for IBM Coherent
+	  Accelerators (CXL).  CXL is otherwise known as Coherent Accelerator
+	  Processor Interface (CAPI).  CAPI allows accelerators in FPGAs to be
+	  coherently attached to a CPU via an MMU.  This driver enables
+	  userspace programs to access these accelerators via /dev/cxl/afuM.N
+	  devices.
+
+	  CAPI adapters are found in POWER8 based systems.
+
+	  If unsure, say N.
