12 config SERIAL_AMBA_PL010
13 tristate "ARM AMBA PL010 serial port support"
14 depends on ARM_AMBA && (BROKEN || !ARCH_VERSATILE)
17 This selects the ARM(R) AMBA(R) PrimeCell PL010 UART. If you have
18 an Integrator/AP or Integrator/PP2 platform, or if you have a
19 Cirrus Logic EP93xx CPU, say Y or M here.
23 config SERIAL_AMBA_PL010_CONSOLE
24 bool "Support for console on AMBA serial port"
25 depends on SERIAL_AMBA_PL010=y
26 select SERIAL_CORE_CONSOLE
28 Say Y here if you wish to use an AMBA PrimeCell UART as the system
29 console (the system console is the device which receives all kernel
30 messages and warnings and which allows logins in single user mode).
32 Even if you say Y here, the currently visible framebuffer console
33 (/dev/tty0) will still be used as the system console by default, but
34 you can alter that using a kernel command line option such as
35 "console=ttyAM0". (Try "man bootparam" or see the documentation of

66 config SERIAL_SB1250_DUART
67 tristate "BCM1xxx on-chip DUART serial support"
68 depends on SIBYTE_SB1xxx_SOC=y
72 Support for the asynchronous serial interface (DUART) included in
73 the BCM1250 and derived System-On-a-Chip (SOC) devices. Note that
74 the letter D in DUART stands for "dual", which is how the device
75 is implemented. Depending on the SOC configuration there may be
76 one or more DUARTs available of which all are handled.
78 If unsure, say Y. To compile this driver as a module, choose M here:
79 the module will be called sb1250-duart.
81 config SERIAL_SB1250_DUART_CONSOLE
82 bool "Support for console on a BCM1xxx DUART serial port"
83 depends on SERIAL_SB1250_DUART=y
84 select SERIAL_CORE_CONSOLE
87 If you say Y here, it will be possible to use a serial port as the
88 system console (the system console is the device which receives all
89 kernel messages and warnings and which allows logins in single user
95 bool "AT91 / AT32 on-chip serial port support"
96 depends on ARCH_AT91 || AVR32
99 This enables the driver for the on-chip UARTs of the Atmel
100 AT91 and AT32 processors.
102 config SERIAL_ATMEL_CONSOLE
103 bool "Support for console on AT91 / AT32 serial port"
104 depends on SERIAL_ATMEL=y
105 select SERIAL_CORE_CONSOLE
107 Say Y here if you wish to use an on-chip UART on a Atmel
108 AT91 or AT32 processor as the system console (the system
109 console is the device which receives all kernel messages and
110 warnings and which allows logins in single user mode).
112 config SERIAL_ATMEL_PDC
113 bool "Support DMA transfers on AT91 / AT32 serial port"
114 depends on SERIAL_ATMEL
117 Say Y here if you wish to use the PDC to do DMA transfers to
118 and from the Atmel AT91 / AT32 serial port. In order to
119 actually use DMA transfers, make sure that the use_dma_tx
120 and use_dma_rx members in the atmel_uart_data struct is set
121 appropriately for each port.
123 Note that break and error handling currently doesn't work
124 properly when DMA is enabled. Make sure that ports where
125 this matters don't use DMA.
127 config SERIAL_ATMEL_TTYAT
128 bool "Install as device ttyATn instead of ttySn"
129 depends on SERIAL_ATMEL=y
131 Say Y here if you wish to have the internal AT91 / AT32 UARTs
132 appear as /dev/ttyATn (major 204, minor starting at 154)
133 instead of the normal /dev/ttySn (major 4, minor starting at
134 64). This is necessary if you also want other UARTs, such as
135 external 8250/16C550 compatible UARTs.
136 The ttySn nodes are legally reserved for the 8250 serial driver
137 but are often misused by other serial drivers.
139 To use this, you should create suitable ttyATn device nodes in
140 /dev/, and pass "console=ttyATn" to the kernel.
142 Say Y if you have an external 8250/16C550 UART. If unsure, say N.
144 config SERIAL_KGDB_NMI
145 bool "Serial console over KGDB NMI debugger port"
146 depends on KGDB_SERIAL_CONSOLE
148 This special driver allows you to temporary use NMI debugger port
149 as a normal console (assuming that the port is attached to KGDB).
151 Unlike KDB's disable_nmi command, with this driver you are always
152 able to go back to the debugger using KGDB escape sequence ($3#33).
153 This is because this console driver processes the input in NMI
154 context, and thus is able to intercept the magic sequence.
156 Note that since the console interprets input and uses polling
157 communication methods, for things like PPP you still must fully
158 detach debugger port from the KGDB NMI (i.e. disable_nmi), and
164 bool "Micrel KS8695 (Centaur) serial port support"

176 system console (the system console is the device which
177 receives all kernel messages and warnings and which allows
178 logins in single user mode).

181 tristate "CLPS711X serial port support"
182 depends on ARCH_CLPS711X
186 This enables the driver for the on-chip UARTs of the Cirrus
187 Logic EP711x/EP721x/EP731x processors.

190 bool "Support for console on CLPS711X serial port"
191 depends on SERIAL_CLPS711X=y

277 Support for the on-chip UARTs on the NVIDIA Tegra series SOCs
278 providing /dev/ttyHS0, 1, 2, 3 and 4 (note, some machines may not
279 provide all of these ports, depending on how the serial port
280 are enabled). This driver uses the APB DMA to achieve higher baudrate
281 and better performance.

823 both z85C30 and 8250 type ports at the same time.
825 If this option is not selected, the pmac_zilog driver will

827 the pmac_zilog and 8250 drivers to co-exist, but may cause
828 existing userspace setups to break. Programs that need to
829 access the built-in serial ports on powermacs will need to
830 be reconfigured to use /dev/ttyPZn instead of /dev/ttySn.
