+          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.
