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"
119 depends on ARCH_AT91 || AVR32 || COMPILE_TEST

124 AT91 and AT32 processors.

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

199 Say Y here if you wish to use a KS8695 (Centaur) UART as the
200 system console (the system console is the device which
201 receives all kernel messages and warnings and which allows
202 logins in single user mode).

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

324 and better performance.
