26 This selects the ARM(R) AMBA(R) PrimeCell PL010 UART. If you have

77 depends on SIBYTE_SB1xxx_SOC=y
81 Support for the asynchronous serial interface (DUART) included in
82 the BCM1250 and derived System-On-a-Chip (SOC) devices. Note that
83 the letter D in DUART stands for "dual", which is how the device
84 is implemented. Depending on the SOC configuration there may be
85 one or more DUARTs available of which all are handled.
87 If unsure, say Y. To compile this driver as a module, choose M here:
88 the module will be called sb1250-duart.

123 depends on SERIAL_ATMEL
126 Say Y here if you wish to use the PDC to do DMA transfers to
127 and from the Atmel AT91 / AT32 serial port. In order to
128 actually use DMA transfers, make sure that the use_dma_tx
129 and use_dma_rx members in the atmel_uart_data struct is set
130 appropriately for each port.
132 Note that break and error handling currently doesn't work
133 properly when DMA is enabled. Make sure that ports where
134 this matters don't use DMA.

140 Say Y here if you wish to have the internal AT91 / AT32 UARTs
141 appear as /dev/ttyATn (major 204, minor starting at 154)
142 instead of the normal /dev/ttySn (major 4, minor starting at
143 64). This is necessary if you also want other UARTs, such as
144 external 8250/16C550 compatible UARTs.
145 The ttySn nodes are legally reserved for the 8250 serial driver
146 but are often misused by other serial drivers.
148 To use this, you should create suitable ttyATn device nodes in
149 /dev/, and pass "console=ttyATn" to the kernel.

153 config SERIAL_KGDB_NMI
154 bool "Serial console over KGDB NMI debugger port"
155 depends on KGDB_SERIAL_CONSOLE
157 This special driver allows you to temporary use NMI debugger port
158 as a normal console (assuming that the port is attached to KGDB).
160 Unlike KDB's disable_nmi command, with this driver you are always
161 able to go back to the debugger using KGDB escape sequence ($3#33).
162 This is because this console driver processes the input in NMI
163 context, and thus is able to intercept the magic sequence.
165 Note that since the console interprets input and uses polling
166 communication methods, for things like PPP you still must fully
167 detach debugger port from the KGDB NMI (i.e. disable_nmi), and

837 existing userspace setups to break. Programs that need to
838 access the built-in serial ports on powermacs will need to

1471 tristate "Comtrol RocketPort EXPRESS/INFINITY support"
1475 This driver supports the Comtrol RocketPort EXPRESS and
1476 RocketPort INFINITY families of PCI/PCIe multiport serial adapters.
1477 These adapters use a "RocketPort 2" ASIC that is not compatible
1478 with the original RocketPort driver (CONFIG_ROCKETPORT).
1480 To compile this driver as a module, choose M here: the
1481 module will be called rp2.
1483 If you want to compile this driver into the kernel, say Y here. If
1484 you don't have a suitable RocketPort card installed, say N.
1486 config SERIAL_RP2_NR_UARTS
1487 int "Maximum number of RocketPort EXPRESS/INFINITY ports"
1488 depends on SERIAL_RP2
1491 If multiple cards are present, the default limit of 32 ports may
1492 need to be increased.
