+ Say Y here if you wish to have the internal UARTs appear as
+ /dev/ttyAT0-N (major 204, minor 154-169) instead of the
+ normal /dev/ttyS0-4 (major 4, minor 64-255). 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.
