This is a driver for the SB1250 DUART, a dual serial port implementation included in the Broadcom family of SOCs descending from the SiByte SB1250 MIPS64 chip multiprocessor. It is a new implementation replacing the old-fashioned driver currently present in the linux-mips.org tree. It supports all the usual features one would expect from a(n asynchronous) serial driver, including modem line control (as far as hardware supports it -- there is edge detection logic missing from the DCD and RI lines and the driver does not implement polling of these lines at the moment), the serial console, BREAK transmission and reception, including the magic SysRq. The receive FIFO threshold is not maintained though. The driver was tested with a SWARM board which uses a BCM1250 SOC (which is dual MIPS64 CMP) and has both ports of the single DUART implemented wired externally. Both were tested. Testing included using the ports as terminal lines at 1200bps (which is the ports minimum), 115200bps and a couple of random speeds inbetween. The modem lines were verified to operate correctly. No testing was performed with a use as a network interface, like with SLIP or PPP. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Acked-by: Ralf Baechle <ralf@linux-mips.org> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This selects whether you want to include the driver for the standard
|
|
serial ports. The standard answer is Y. People who might say N
|
|
here are those that are setting up dedicated Ethernet WWW/FTP
|
|
servers, or users that have one of the various bus mice instead of a
|
|
serial mouse and don't intend to use their machine's standard serial
|
|
port for anything. (Note that the Cyclades and Stallion multi
|
|
serial port drivers do not need this driver built in for them to
|
|
work.)
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called 8250.
|
|
[WARNING: Do not compile this driver as a module if you are using
|
|
non-standard serial ports, since the configuration information will
|
|
be lost when the driver is unloaded. This limitation may be lifted
|
|
in the future.]
|
|
|
|
BTW1: If you have a mouseman serial mouse which is not recognized by
|
|
the X window system, try running gpm first.
|
|
|
|
BTW2: If you intend to use a software modem (also called Winmodem)
|
|
under Linux, forget it. These modems are crippled and require
|
|
proprietary drivers which are only available under Windows.
|
|
|
|
Most people will say Y or M here, so that they can use serial mice,
|
|
modems and similar devices connecting to the standard serial ports.

If you say Y here, it will be possible to use a serial port as the

system console (the system console is the device which receives all
|
|
kernel messages and warnings and which allows logins in single user
|
|
mode). This could be useful if some terminal or printer is connected
|
|
to that serial port.
|
|
|
|
Even if you say Y here, the currently visible virtual console
|
|
(/dev/tty0) will still be used as the system console by default, but
|
|
you can alter that using a kernel command line option such as
|
|
"console=ttyS1". (Try "man bootparam" or see the documentation of
|
|
your boot loader (grub or lilo or loadlin) about how to pass options
|
|
to the kernel at boot time.)
|
|
|
|
If you don't have a VGA card installed and you say Y here, the
|
|
kernel will automatically use the first serial line, /dev/ttyS0, as
|
|
system console.
|
|
|

you can set that using a kernel command line option such as

"console=uart8250,io,0x3f8,9600n8"
|
|
"console=uart8250,mmio,0xff5e0000,115200n8".

"earlycon=uart8250,mmio,0xff5e0000,115200n8".

it will not only setup early console.

Say Y here if you wish to use one of the serial ports as the

system console--the system console is the device which

receives all kernel messages and warnings and which allows
|
|
logins in single user mode.

Even if you say Y here, the currently visible framebuffer console
|
|
(/dev/tty0) will still be used as the default system console, but
|

you can alter that using a kernel command line, for example
|
|
"console=ttyAM1".
