	  This enables support for systems with more than one CPU. If you have
	  a system with only one CPU, say N. If you have a system with more
	  than one CPU, say Y.

	  If you say N here, the kernel will run on uni- and multiprocessor
	  machines, but will use only one CPU of a multiprocessor machine. If
	  you say Y here, the kernel will run on many, but not all,
	  uniprocessor machines. On a uniprocessor machine, the kernel
	  will run faster if you say N here.

	  People using multiprocessor machines who say Y here should also say
	  Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
	  Management" code will be disabled if you say Y here.

	  See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO

	  This kernel feature is useful for number crunching applications
	  that may need to compute untrusted bytecode during their
	  execution. By using pipes or other transports made available to
	  the process as file descriptors supporting the read/write
	  syscalls, it's possible to isolate those applications in
	  their own address space using seccomp. Once seccomp is
	  enabled via /proc/<pid>/seccomp, it cannot be disabled
	  and the task is only allowed to execute a few safe syscalls
	  defined by each seccomp mode.

	  This driver toggles the front-panel LED on sun4m systems

	  via writes to /proc/led

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.

	  The LEON processor is a synthesizable VHDL model of the
	  SPARC-v8 standard. LEON is  part of the GRLIB collection of
	  IP cores that are distributed under GPL. GRLIB can be downloaded
	  from www.gaisler.com. You can download a sparc-linux cross-compilation
	  toolchain at www.gaisler.com.

	---help---
	 Optional setting only affecting the uImage.o ELF-image used to
	 download the uImage file to the target using a ELF-loader other than
	 U-Boot. It may for example be used to download an uImage to FLASH with
	 the GRMON utility before even starting u-boot.

config UBOOT_ENTRY_ADDR

	 Do not change this unless you know what you're doing. This is
