  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
  24           module will be called 8250.
  25           [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.

  43         select SERIAL_CORE_CONSOLE
  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
  62           You can set that using a kernel command line option such as
  63           "console=uart8250,io,0x3f8,9600n8"
  64           "console=uart8250,mmio,0xff5e0000,115200n8".
  65           and it will switch to normal serial console when the corresponding
  66           port is ready.
  67           "earlycon=uart8250,io,0x3f8,9600n8"
  68           "earlycon=uart8250,mmio,0xff5e0000,115200n8".
  69           it will not only setup early console.

1577           This driver is for PCH(Platform controller Hub) UART of Intel EG20T
1578           which is an IOH(Input/Output Hub) for x86 embedded processor.
1579           Enabling PCH_DMA, this PCH UART works as DMA mode.

1581           This driver also can be used for OKI SEMICONDUCTOR IOH(Input/
1582           Output Hub), ML7213 and ML7223.
1583           ML7213 IOH is for IVI(In-Vehicle Infotainment) use and ML7223 IOH is
1584           for MP(Media Phone) use.
1585           ML7213/ML7223 is companion chip for Intel Atom E6xx series.
1586           ML7213/ML7223 is completely compatible for Intel EG20T PCH.
