	  NOTE: This option WILL override the PROM bootargs setting!

config SERIAL_CONSOLE
	bool
	depends on SPARC32
	default y
	---help---
	  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 (silo) about how to pass options to the kernel at
	  boot time.)

	  If you don't have a graphics card installed and you say Y here, the
	  kernel will automatically use the first serial line, /dev/ttyS0, as
	  system console.

	  If unsure, say N.

	help
	  Find out whether your system includes a PCI bus. PCI is the name of
	  a bus system, i.e. the way the CPU talks to the other stuff inside
	  your box.  If you say Y here, the kernel will include drivers and
	  infrastructure code to support PCI bus devices.

	  CONFIG_PCI is needed for all JavaStation's (including MrCoffee),
	  CP-1200, JavaEngine-1, Corona, Red October, and Serengeti SGSC.
	  All of these platforms are extremely obscure, so say N if unsure.

	  -t openpromfs none /proc/openprom".

	  To compile the /proc/openprom support as a module, choose M here: the
	  module will be called openpromfs.

	  Only choose N if you know in advance that you will not need to modify
	  OpenPROM settings on the running system.
