107 Support for the asynchronous serial interface (DUART) included in
108 the BCM1250 and derived System-On-a-Chip (SOC) devices. Note that
109 the letter D in DUART stands for "dual", which is how the device
110 is implemented. Depending on the SOC configuration there may be
111 one or more DUARTs available of which all are handled.

156 actually use DMA transfers, make sure that the use_dma_tx
157 and use_dma_rx members in the atmel_uart_data struct is set

160 Note that break and error handling currently doesn't work
161 properly when DMA is enabled. Make sure that ports where
162 this matters don't use DMA.

168 Say Y here if you wish to have the internal AT91 UARTs
169 appear as /dev/ttyATn (major 204, minor starting at 154)
170 instead of the normal /dev/ttySn (major 4, minor starting at
171 64). This is necessary if you also want other UARTs, such as
172 external 8250/16C550 compatible UARTs.
173 The ttySn nodes are legally reserved for the 8250 serial driver
174 but are often misused by other serial drivers.
176 To use this, you should create suitable ttyATn device nodes in
177 /dev/, and pass "console=ttyATn" to the kernel.

181 config SERIAL_KGDB_NMI
182 bool "Serial console over KGDB NMI debugger port"
183 depends on KGDB_SERIAL_CONSOLE
185 This special driver allows you to temporary use NMI debugger port
186 as a normal console (assuming that the port is attached to KGDB).
188 Unlike KDB's disable_nmi command, with this driver you are always
189 able to go back to the debugger using KGDB escape sequence ($3#33).
190 This is because this console driver processes the input in NMI
191 context, and thus is able to intercept the magic sequence.
193 Note that since the console interprets input and uses polling
194 communication methods, for things like PPP you still must fully
195 detach debugger port from the KGDB NMI (i.e. disable_nmi), and
