13 ---help---
14 This selects whether you want to include the driver for the standard
15 serial ports. The standard answer is Y. People who might say N
16 here are those that are setting up dedicated Ethernet WWW/FTP
17 servers, or users that have one of the various bus mice instead of a
18 serial mouse and don't intend to use their machine's standard serial
19 port for anything. (Note that the Cyclades and Stallion multi
20 serial port drivers do not need this driver built in for them to
21 work.)
22
23 To compile this driver as a module, choose M here: the
Timothy Charles McGrathdf7559d2006-01-23 09:50:09 +000024 module will be called 8250.
Linus Torvalds1da177e2005-04-16 15:20:36 -070025 [WARNING: Do not compile this driver as a module if you are using
26 non-standard serial ports, since the configuration information will
27 be lost when the driver is unloaded. This limitation may be lifted
28 in the future.]
29
30 BTW1: If you have a mouseman serial mouse which is not recognized by
31 the X window system, try running gpm first.
32
33 BTW2: If you intend to use a software modem (also called Winmodem)
34 under Linux, forget it. These modems are crippled and require
35 proprietary drivers which are only available under Windows.
36
37 Most people will say Y or M here, so that they can use serial mice,
38 modems and similar devices connecting to the standard serial ports.

44 ---help---
45 If you say Y here, it will be possible to use a serial port as the
46 system console (the system console is the device which receives all
47 kernel messages and warnings and which allows logins in single user
48 mode). This could be useful if some terminal or printer is connected
49 to that serial port.
50
51 Even if you say Y here, the currently visible virtual console
52 (/dev/tty0) will still be used as the system console by default, but
53 you can alter that using a kernel command line option such as
54 "console=ttyS1". (Try "man bootparam" or see the documentation of
55 your boot loader (grub or lilo or loadlin) about how to pass options
56 to the kernel at boot time.)
57
58 If you don't have a VGA card installed and you say Y here, the
59 kernel will automatically use the first serial line, /dev/ttyS0, as
60 system console.
61
Matt LaPlante01dd2fb2007-10-20 01:34:40 +020062 You can set that using a kernel command line option such as
Yinghai Lu18a8bd92007-07-15 23:37:59 -070063 "console=uart8250,io,0x3f8,9600n8"
64 "console=uart8250,mmio,0xff5e0000,115200n8".
Matt LaPlante01dd2fb2007-10-20 01:34:40 +020065 and it will switch to normal serial console when the corresponding
66 port is ready.
Yinghai Lu18a8bd92007-07-15 23:37:59 -070067 "earlycon=uart8250,io,0x3f8,9600n8"
68 "earlycon=uart8250,mmio,0xff5e0000,115200n8".
69 it will not only setup early console.

Haavard Skinnemoenacca9b82006-10-04 16:02:09 +0200398 Say Y here if you wish to have the internal AT91 / AT32 UARTs
399 appear as /dev/ttyATn (major 204, minor starting at 154)
400 instead of the normal /dev/ttySn (major 4, minor starting at
401 64). This is necessary if you also want other UARTs, such as
402 external 8250/16C550 compatible UARTs.
Andrew Victor1e6c9c22006-01-10 16:59:27 +0000403 The ttySn nodes are legally reserved for the 8250 serial driver
404 but are often misused by other serial drivers.
405
406 To use this, you should create suitable ttyATn device nodes in
407 /dev/, and pass "console=ttyATn" to the kernel.
408
409 Say Y if you have an external 8250/16C550 UART. If unsure, say N.

1546 Altera UART ports. The usual default varies from board to board,
1547 and this setting is a way of catering for that.

1567 This driver is for PCH(Platform controller Hub) UART of Intel EG20T
1568 which is an IOH(Input/Output Hub) for x86 embedded processor.
1569 Enabling PCH_DMA, this PCH UART works as DMA mode.

Tomoya MORINAGA8249f742011-10-28 09:38:49 +09001571 This driver also can be used for LAPIS Semiconductor IOH(Input/
1572 Output Hub), ML7213, ML7223 and ML7831.
1573 ML7213 IOH is for IVI(In-Vehicle Infotainment) use, ML7223 IOH is
1574 for MP(Media Phone) use and ML7831 IOH is for general purpose use.
1575 ML7213/ML7223/ML7831 is companion chip for Intel Atom E6xx series.
1576 ML7213/ML7223/ML7831 is completely compatible for Intel EG20T PCH.
