+        help
+          Say Y here if you wish to have the five internal AT91RM9200 UARTs
+          appear as /dev/ttyAT0-4 (major 240, minor 0-4) instead of the
+          normal /dev/ttyS0-4 (major 4, minor 64-68). This is necessary if
+          you also want other UARTs, such as external 8250/16C550 compatible
+          UARTs.
+          The ttySn nodes are legally reserved for the 8250 serial driver
+          but are often misused by other serial drivers.
+
+          To use this, you should create suitable ttyATn device nodes in
+          /dev/, and pass "console=ttyATn" to the kernel.
+
+          Say Y if you have an external 8250/16C550 UART.  If unsure, say N.
