+        help
+          Depending on the arch implementation of hardware breakpoints,
+          some of them have separate registers for data and instruction
+          breakpoints addresses, others have mixed registers to store
+          them but define the access type in a control register.
+          Select this option if your arch implements breakpoints under the
+          latter fashion.
