++ 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.
