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

21 Cirrus Logic EP93xx CPU, say Y or M here.

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.

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.

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

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