14 config SERIAL_AMBA_PL010
15 tristate "ARM AMBA PL010 serial port support"
16 depends on ARM_AMBA && (BROKEN || !ARCH_VERSATILE)
19 This selects the ARM(R) AMBA(R) PrimeCell PL010 UART. If you have
20 an Integrator/AP or Integrator/PP2 platform, or if you have a
21 Cirrus Logic EP93xx CPU, say Y or M here.
25 config SERIAL_AMBA_PL010_CONSOLE
26 bool "Support for console on AMBA serial port"
27 depends on SERIAL_AMBA_PL010=y
28 select SERIAL_CORE_CONSOLE
30 Say Y here if you wish to use an AMBA PrimeCell UART as the system
31 console (the system console is the device which receives all kernel
32 messages and warnings and which allows logins in single user mode).
34 Even if you say Y here, the currently visible framebuffer console
35 (/dev/tty0) will still be used as the system console by default, but
36 you can alter that using a kernel command line option such as
37 "console=ttyAM0". (Try "man bootparam" or see the documentation of
38 your boot loader (lilo or loadlin) about how to pass options to the
41 config SERIAL_AMBA_PL011
42 tristate "ARM AMBA PL011 serial port support"

68 config SERIAL_SB1250_DUART
69 tristate "BCM1xxx on-chip DUART serial support"
70 depends on SIBYTE_SB1xxx_SOC=y
74 Support for the asynchronous serial interface (DUART) included in
75 the BCM1250 and derived System-On-a-Chip (SOC) devices. Note that
76 the letter D in DUART stands for "dual", which is how the device
77 is implemented. Depending on the SOC configuration there may be
78 one or more DUARTs available of which all are handled.
80 If unsure, say Y. To compile this driver as a module, choose M here:
81 the module will be called sb1250-duart.
83 config SERIAL_SB1250_DUART_CONSOLE
84 bool "Support for console on a BCM1xxx DUART serial port"
85 depends on SERIAL_SB1250_DUART=y
86 select SERIAL_CORE_CONSOLE
89 If you say Y here, it will be possible to use a serial port as the
90 system console (the system console is the device which receives all
91 kernel messages and warnings and which allows logins in single user
97 bool "AT91 / AT32 on-chip serial port support"
98 depends on ARCH_AT91 || AVR32
101 This enables the driver for the on-chip UARTs of the Atmel
102 AT91 and AT32 processors.
104 config SERIAL_ATMEL_CONSOLE
105 bool "Support for console on AT91 / AT32 serial port"
106 depends on SERIAL_ATMEL=y
107 select SERIAL_CORE_CONSOLE
109 Say Y here if you wish to use an on-chip UART on a Atmel
110 AT91 or AT32 processor as the system console (the system
111 console is the device which receives all kernel messages and
112 warnings and which allows logins in single user mode).
114 config SERIAL_ATMEL_PDC
115 bool "Support DMA transfers on AT91 / AT32 serial port"
116 depends on SERIAL_ATMEL
119 Say Y here if you wish to use the PDC to do DMA transfers to
120 and from the Atmel AT91 / AT32 serial port. In order to
121 actually use DMA transfers, make sure that the use_dma_tx
122 and use_dma_rx members in the atmel_uart_data struct is set
123 appropriately for each port.
125 Note that break and error handling currently doesn't work
126 properly when DMA is enabled. Make sure that ports where
127 this matters don't use DMA.
129 config SERIAL_ATMEL_TTYAT
130 bool "Install as device ttyATn instead of ttySn"
131 depends on SERIAL_ATMEL=y
133 Say Y here if you wish to have the internal AT91 / AT32 UARTs
134 appear as /dev/ttyATn (major 204, minor starting at 154)
135 instead of the normal /dev/ttySn (major 4, minor starting at
136 64). This is necessary if you also want other UARTs, such as
137 external 8250/16C550 compatible UARTs.
138 The ttySn nodes are legally reserved for the 8250 serial driver
139 but are often misused by other serial drivers.
141 To use this, you should create suitable ttyATn device nodes in
142 /dev/, and pass "console=ttyATn" to the kernel.
144 Say Y if you have an external 8250/16C550 UART. If unsure, say N.
146 config SERIAL_KGDB_NMI
147 bool "Serial console over KGDB NMI debugger port"
148 depends on KGDB_SERIAL_CONSOLE
150 This special driver allows you to temporary use NMI debugger port
151 as a normal console (assuming that the port is attached to KGDB).
153 Unlike KDB's disable_nmi command, with this driver you are always
154 able to go back to the debugger using KGDB escape sequence ($3#33).
155 This is because this console driver processes the input in NMI
156 context, and thus is able to intercept the magic sequence.
158 Note that since the console interprets input and uses polling
159 communication methods, for things like PPP you still must fully
160 detach debugger port from the KGDB NMI (i.e. disable_nmi), and
166 bool "Micrel KS8695 (Centaur) serial port support"
167 depends on ARCH_KS8695

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

183 tristate "CLPS711X serial port support"
184 depends on ARCH_CLPS711X || COMPILE_TEST

188 Logic EP711x/EP721x/EP731x processors.

278 Support for the on-chip UARTs on the NVIDIA Tegra series SOCs
279 providing /dev/ttyTHS0, 1, 2, 3 and 4 (note, some machines may not
280 provide all of these ports, depending on how the serial port
281 are enabled). This driver uses the APB DMA to achieve higher baudrate
282 and better performance.

820 The pmac_zilog driver for the z85C30 chip on many powermacs
821 historically used the device numbers for /dev/ttySn. The
822 8250 serial port driver also uses these numbers, which means
823 the two drivers being unable to coexist; you could not use
824 both z85C30 and 8250 type ports at the same time.
826 If this option is not selected, the pmac_zilog driver will
827 use the device numbers allocated for /dev/ttyPZn. This allows
828 the pmac_zilog and 8250 drivers to co-exist, but may cause
829 existing userspace setups to break. Programs that need to
830 access the built-in serial ports on powermacs will need to
831 be reconfigured to use /dev/ttyPZn instead of /dev/ttySn.
833 If you enable this option, any z85c30 ports in the system will
834 be registered as ttyS0 onwards as in the past, and you will be

1470 you don't have a suitable RocketPort card installed, say N.
1472 config SERIAL_RP2_NR_UARTS
1473 int "Maximum number of RocketPort EXPRESS/INFINITY ports"
1474 depends on SERIAL_RP2
1477 If multiple cards are present, the default limit of 32 ports may
1478 need to be increased.
1480 config SERIAL_FSL_LPUART
1481 tristate "Freescale lpuart serial port support"
1484 Support for the on-chip lpuart on some Freescale SOCs.
1486 config SERIAL_FSL_LPUART_CONSOLE
1487 bool "Console on Freescale lpuart serial port"
1488 depends on SERIAL_FSL_LPUART=y
1489 select SERIAL_CORE_CONSOLE
1491 If you have enabled the lpuart serial port on the Freescale SoCs,
1492 you can make it the console by answering Y to this option.
1494 config SERIAL_ST_ASC
1495 tristate "ST ASC serial port support"
1497 depends on ARM || COMPILE_TEST
1499 This driver is for the on-chip Asychronous Serial Controller on
1500 STMicroelectronics STi SoCs.
1501 ASC is embedded in ST COMMS IP block. It supports Rx & Tx functionality.
1502 It support all industry standard baud rates.
1506 config SERIAL_ST_ASC_CONSOLE
1507 bool "Support for console on ST ASC"
1508 depends on SERIAL_ST_ASC=y
