21 config SERIAL_AMBA_PL010
22 tristate "ARM AMBA PL010 serial port support"
26 This selects the ARM(R) AMBA(R) PrimeCell PL010 UART. If you have
27 an Integrator/AP or Integrator/PP2 platform, or if you have a
28 Cirrus Logic EP93xx CPU, say Y or M here.

37 Say Y here if you wish to use an AMBA PrimeCell UART as the system
38 console (the system console is the device which receives all kernel
39 messages and warnings and which allows logins in single user mode).
41 Even if you say Y here, the currently visible framebuffer console
42 (/dev/tty0) will still be used as the system console by default, but

77 bool "Early console using ARM semihosting"
78 depends on ARM64 || ARM
80 select SERIAL_CORE_CONSOLE
81 select SERIAL_EARLYCON
83 Support for early debug console using ARM semihosting. This enables
84 the console before standard serial driver is probed. This is enabled
85 with "earlycon=smh" on the kernel command line. The console is
86 enabled when early_param is processed.
88 config SERIAL_SB1250_DUART
89 tristate "BCM1xxx on-chip DUART serial support"
90 depends on SIBYTE_SB1xxx_SOC=y
94 Support for the asynchronous serial interface (DUART) included in
95 the BCM1250 and derived System-On-a-Chip (SOC) devices. Note that
96 the letter D in DUART stands for "dual", which is how the device
97 is implemented. Depending on the SOC configuration there may be
98 one or more DUARTs available of which all are handled.
100 If unsure, say Y. To compile this driver as a module, choose M here:
101 the module will be called sb1250-duart.
103 config SERIAL_SB1250_DUART_CONSOLE
104 bool "Support for console on a BCM1xxx DUART serial port"
105 depends on SERIAL_SB1250_DUART=y

110 system console (the system console is the device which receives all
111 kernel messages and warnings and which allows logins in single user
117 bool "AT91 / AT32 on-chip serial port support"
118 depends on ARCH_AT91 || AVR32 || COMPILE_TEST
120 select SERIAL_MCTRL_GPIO if GPIOLIB
122 This enables the driver for the on-chip UARTs of the Atmel
123 AT91 and AT32 processors.

126 bool "Support for console on AT91 / AT32 serial port"
127 depends on SERIAL_ATMEL=y
128 select SERIAL_CORE_CONSOLE
130 Say Y here if you wish to use an on-chip UART on a Atmel
131 AT91 or AT32 processor as the system console (the system
132 console is the device which receives all kernel messages and
133 warnings and which allows logins in single user mode).
135 config SERIAL_ATMEL_PDC
136 bool "Support DMA transfers on AT91 / AT32 serial port"
137 depends on SERIAL_ATMEL
140 Say Y here if you wish to use the PDC to do DMA transfers to
141 and from the Atmel AT91 / AT32 serial port. In order to
142 actually use DMA transfers, make sure that the use_dma_tx
143 and use_dma_rx members in the atmel_uart_data struct is set
144 appropriately for each port.
146 Note that break and error handling currently doesn't work
147 properly when DMA is enabled. Make sure that ports where
148 this matters don't use DMA.
150 config SERIAL_ATMEL_TTYAT
151 bool "Install as device ttyATn instead of ttySn"
152 depends on SERIAL_ATMEL=y
154 Say Y here if you wish to have the internal AT91 / AT32 UARTs
155 appear as /dev/ttyATn (major 204, minor starting at 154)
156 instead of the normal /dev/ttySn (major 4, minor starting at
157 64). This is necessary if you also want other UARTs, such as
158 external 8250/16C550 compatible UARTs.
159 The ttySn nodes are legally reserved for the 8250 serial driver
160 but are often misused by other serial drivers.
162 To use this, you should create suitable ttyATn device nodes in
163 /dev/, and pass "console=ttyATn" to the kernel.
165 Say Y if you have an external 8250/16C550 UART. If unsure, say N.
167 config SERIAL_KGDB_NMI
168 bool "Serial console over KGDB NMI debugger port"
169 depends on KGDB_SERIAL_CONSOLE
171 This special driver allows you to temporary use NMI debugger port
172 as a normal console (assuming that the port is attached to KGDB).
174 Unlike KDB's disable_nmi command, with this driver you are always
175 able to go back to the debugger using KGDB escape sequence ($3#33).
176 This is because this console driver processes the input in NMI
177 context, and thus is able to intercept the magic sequence.
179 Note that since the console interprets input and uses polling
180 communication methods, for things like PPP you still must fully
181 detach debugger port from the KGDB NMI (i.e. disable_nmi), and
187 bool "Micrel KS8695 (Centaur) serial port support"
188 depends on ARCH_KS8695
191 This selects the Micrel Centaur KS8695 UART. Say Y here.

194 bool "Support for console on KS8695 (Centaur) serial port"
195 depends on SERIAL_KS8695=y
196 select SERIAL_CORE_CONSOLE
198 Say Y here if you wish to use a KS8695 (Centaur) UART as the
199 system console (the system console is the device which
200 receives all kernel messages and warnings and which allows
201 logins in single user mode).

319 providing /dev/ttyTHS0, 1, 2, 3 and 4 (note, some machines may not

322 and better performance.
