	bool
	default y
	help
	  uClinux is the MMU-less version of Linux Kernel.

	  The ARM series is a line of low-power-consumption RISC chip designs
	  licensed by ARM ltd and targeted at embedded applications and
	  handhelds such as the Compaq IPAQ.  ARM-based PCs are no longer
	  manufactured, but  legacy ARM-based PC hardware remains popular in
	  Europe.

	  There is an ARM(w/MMU) Linux project with a web page at
	  <http://www.arm.linux.org.uk/>.

	  The recent cores are designed to address a wide variety of applications.
	  Many cores for application platform have Memory Mangement Unit(MMU),
	  however, other cores for embedded systems, secure application have
	  only MPU or even NONE, although heavily used in many SoCs.

	  There is an ARM(w/o MMU) uClinux project with a web page at
	  <http://adam.kaist.ac.kr/~hschoe/>.

config MMU
	bool
	default n
	help
	  We don't use paged MMU here. 

config MPU
	bool
	help
	  Some cores of ARM series have Memory Processing Unit(MPU).
	  Refer your core manual.

	  Say Y here if your ARM core has MPU.

	  Otherwise, say N.

config EISA
	bool
	---help---
	  The Extended Industry Standard Architecture (EISA) bus was
	  developed as an open alternative to the IBM MicroChannel bus.

	  The EISA bus provided some of the features of the IBM MicroChannel
	  bus while maintaining backward compatibility with cards made for
	  the older ISA bus.  The EISA bus saw limited use between 1988 and
	  1995 when it was made obsolete by the PCI bus.

	  Say Y here if you are building a kernel for an EISA-based machine.

	  Otherwise, say N.

config SBUS
	bool

config MCA
	bool
	help
	  MicroChannel Architecture is found in some IBM PS/2 machines and
	  laptops.  It is a bus system similar to PCI or ISA. See
	  <file:Documentation/mca.txt> (and especially the web page given
	  there) before attempting to build an MCA bus kernel.

config PCI
	bool "PCI support"
	default n
	help
	  Find out whether you have a PCI motherboard. PCI is the name of a
	  bus system, i.e. the way the CPU talks to the other stuff inside
	  your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
	  VESA. If you have PCI, say Y, otherwise N.

	  The PCI-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>, contains valuable
	  information about which PCI hardware does work under Linux and which
	  doesn't.

	  Find out whether you have ISA slots on your motherboard.  ISA is the
	  name of a bus system, i.e. the way the CPU talks to the other stuff
	  inside your box.  Other bus systems are PCI, EISA, MicroChannel
	  (MCA) or VESA.  ISA is an older system, now being displaced by PCI;
	  newer boards don't support it.  If you have ISA, say Y, otherwise N.

	help
	  Say Y here if you intend to execute your compressed kernel image (zImage)
	  directly from ROM or flash.  If unsure, say N.

config ZBOOT_ROM_TEXT
	hex "Compressed ROM boot loader base address"
	default "0"

	  The base address for zImage.  Unless you have special requirements, you
	  should not change this value.

config ZBOOT_ROM_BSS

	  you should not change this value.

config CPU_FREQ
	bool "Support CPU clock change (EXPERIMENTAL)"
	depends on (ARCH_S5C7375) && EXPERIMENTAL
	help
	  CPU clock scaling allows you to change the clock speed of the
	  running CPU on the fly. This is a nice method to save battery power,
	  because the lower the clock speed, the less power the CPU
	  consumes. Note that this driver doesn't automatically change the CPU
	  clock speed, you need some userland tools (which still have to be
	  written) to implement the policy. If you don't understand what this
	  is all about, it's safe to say 'N'.

config FPE_NWFPE
	bool "NWFPE math emulation"
	---help---
	  Say Y to include the NWFPE floating point emulator in the kernel.
	  This is necessary to run most binaries. Linux does not currently
	  support floating point hardware so you need to say Y here even if
	  your machine has an FPA or floating point co-processor podule.

	  You may say N here if you are going to load the Acorn FPEmulator
	  early in the bootup.

config FPE_NWFPE_XP
	bool "Support extended precision"
	depends on FPE_NWFPE
	help
	  Say Y to include 80-bit support in the kernel floating-point
	  emulator.  Otherwise, only 32 and 64-bit support is compiled in.
	  Note that gcc does not generate 80-bit operations by default,
	  so in most cases this option only enlarges the size of the
	  floating point emulator without any good reason.

	  You almost surely want to say N here.

config FPE_FASTFPE
	bool "FastFPE math emulation (EXPERIMENTAL)"
	depends on !CPU_32v3 && EXPERIMENTAL
	---help---
	  Say Y here to include the FAST floating point emulator in the kernel.
	  This is an experimental much faster emulator which now also has full
	  precision for the mantissa.  It does not support any exceptions.
	  It is very simple, and approximately 3-6 times faster than NWFPE.

	  It should be sufficient for most programs.  It may be not suitable
	  for scientific calculations, but you have to check this for yourself.
	  If you do not feel you need a faster FP emulation you should better
	  choose NWFPE.

config PM
	bool "Power Management support"
	---help---
	  "Power Management" means that parts of your computer are shut
	  off or put into a power conserving "sleep" mode if they are not
	  being used.  There are two competing standards for doing this: APM
	  and ACPI.  If you want to use either one, say Y here and then also
	  to the requisite support below.

	  Power Management is most important for battery powered laptop
	  computers; if you have a laptop, check out the Linux Laptop home
	  page on the WWW at <http://www.linux-on-laptops.com/> or
	  Tuxmobil - Linux on Mobile Computers at <http://www.tuxmobil.org/>
	  and the Battery Powered Linux mini-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>.

	  Note that, even if you say N here, Linux on the x86 architecture
	  will issue the hlt instruction if nothing is to be done, thereby
	  sending the processor to sleep and saving power.

config PREEMPT
	bool "Preemptible Kernel (EXPERIMENTAL)"
	depends on CPU_32 && EXPERIMENTAL
	help
	  This option reduces the latency of the kernel when reacting to
	  real-time or interactive events by allowing a low priority process to
	  be preempted even if it is in kernel mode executing a system call.
	  This allows applications to run more reliably even when the system is
	  under load.

	  Say Y here if you are building a kernel for a desktop, embedded
	  or real-time system.  Say N if you are unsure.

config APM
	tristate "Advanced Power Management Emulation"
	depends on PM
	---help---
	  APM is a BIOS specification for saving power using several different
	  techniques. This is mostly useful for battery powered laptops with
	  APM compliant BIOSes. If you say Y here, the system time will be
	  reset after a RESUME operation, the /proc/apm device will provide
	  battery status information, and user-space programs will receive
	  notification of APM "events" (e.g. battery status change).

	  If you select "Y" here, you can disable actual use of the APM
	  BIOS by passing the "apm=off" option to the kernel at boot time.

	  Note that the APM support is almost completely disabled for
	  machines with more than one CPU.

	  In order to use APM, you will need supporting software. For location
	  and more information, read <file:Documentation/pm.txt> and the
	  Battery Powered Linux mini-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>.

	  This driver does not spin down disk drives (see the hdparm(8)
	  manpage ("man 8 hdparm") for that), and it doesn't turn off
	  VESA-compliant "green" monitors.

	  This driver does not support the TI 4000M TravelMate and the ACER
	  486/DX4/75 because they don't have compliant BIOSes. Many "green"
	  desktop machines also don't have compliant BIOSes, and this driver
	  may cause those machines to panic during the boot phase.

	  Generally, if you don't have a battery in your machine, there isn't
	  much point in using this driver and you should say N. If you get
	  random kernel OOPSes or reboots that don't seem to be related to
	  anything, try disabling/enabling this option (or disabling/enabling
	  APM in your BIOS).

	  Some other things you should try when experiencing seemingly random,
	  "weird" problems:

	  1) make sure that you have enough swap space and that it is
	  enabled.
	  2) pass the "no-hlt" option to the kernel
	  3) switch on floating point emulation in the kernel and pass
	  the "no387" option to the kernel
	  4) pass the "floppy=nodma" option to the kernel
	  5) pass the "mem=4M" option to the kernel (thereby disabling
	  all but the first 4 MB of RAM)
	  6) make sure that the CPU is not over clocked.
	  7) read the sig11 FAQ at <http://www.bitwizard.nl/sig11/>
	  8) disable the cache from your BIOS settings
	  9) install a fan for the video card or exchange video RAM
	  10) install a better fan for the CPU
	  11) exchange RAM chips
	  12) exchange the motherboard.

	  To compile this driver as a module, choose M here: the
	  module will be called apm.

config CMDLINE
	string "Default kernel command string"
	default ""
	help
	  On some architectures (EBSA110 and CATS), there is currently no way
	  for the boot loader to pass arguments to the kernel. For these
	  architectures, you should supply some command-line options at build
	  time by entering them here. As a minimum, you should specify the
	  memory size and the root device (e.g., mem=64M root=/dev/nfs).

config LEDS
	bool "Timer and CPU usage LEDs"
	depends on ARCH_S5C7375
	help
	  If you say Y here, the LEDs on your machine will be used
	  to provide useful information about your current system status.

	  If you are compiling a kernel for a NetWinder or EBSA-285, you will
	  be able to select which LEDs are active using the options below. If
	  you are compiling a kernel for the EBSA-110 or the LART however, the
	  red LED will simply flash regularly to indicate that the system is
	  still functional. It is safe to say Y here if you have a CATS
	  system, but the driver will do nothing.

config LEDS_TIMER
	bool "Timer LED" if LEDS && ARCH_S5C7375
	depends on ARCH_S5C7375
	help
	  If you say Y here, one of the system LEDs (the green one on the
	  NetWinder, the amber one on the EBSA285, or the red one on the LART)
	  will flash regularly to indicate that the system is still
	  operational. This is mainly useful to kernel hackers who are
	  debugging unstable kernels.

	  The LART uses the same LED for both Timer LED and CPU usage LED
	  functions. You may choose to use both, but the Timer LED function
	  will overrule the CPU usage LED.

config LEDS_CPU
	bool "CPU usage LED"
	depends on LEDS && ARCH_S5C7375
	help
	  If you say Y here, the red LED will be used to give a good real
	  time indication of CPU usage, by lighting whenever the idle task
	  is not currently executing.

	  The LART uses the same LED for both Timer LED and CPU usage LED
	  functions. You may choose to use both, but the Timer LED function
	  will overrule the CPU usage LED.

config ALIGNMENT_TRAP
	bool "Kernel-mode alignment trap handler"
	depends on CPU_32
	default n if ARCH_S3C3410 || ARCH_ATMEL || ARCH_ESPD_4510B
	help
	  ARM processors can not fetch/store information which is not
	  naturally aligned on the bus, i.e., a 4 byte fetch must start at an
	  address divisible by 4. On 32-bit ARM processors, these non-aligned
	  fetch/store instructions will be emulated in software if you say
	  here, which has a severe performance impact. This is necessary for
	  correct operation of some network protocols. With an IP-only
	  configuration it is safe to say N, otherwise say Y.
