specific code in the driver.

Say Y here if you wish to use a UART on the Atmel AT91RM9200 or
AT91SAM9261 as the system console (the system console is the device
which receives all kernel messages and warnings and which allows
logins in single user mode).

Say Y here if you wish to have the five internal AT91RM9200 UARTs
appear as /dev/ttyAT0-4 (major 204, minor 154-158) 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.
Say Y here if you wish to have the internal AT91 / AT32 UARTs
appear as /dev/ttyATn (major 204, minor starting at 154)
instead of the normal /dev/ttySn (major 4, minor starting at
64). 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.
