CONFIG_ARM
  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 Linux project with a web page at
  <http://www.arm.linux.org.uk/>.

CONFIG_LEDS
  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
  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
  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_IDE
  If you say Y here, your kernel will be able to manage low cost mass
  storage units such as ATA/(E)IDE and ATAPI units. The most common
  cases are IDE hard drives and ATAPI CD-ROM drives.

  If your system is pure SCSI and doesn't use these interfaces, you
  can say N here.

  Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
  for mass storage units such as hard disks. It was designed by
  Western Digital and Compaq Computer in 1984. It was then named
  ST506. Quite a number of disks use the IDE interface.

  AT Attachment (ATA) is the superset of the IDE specifications.
  ST506 was also called ATA-1.

  Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
  ATA-3. It provides support for larger disks (up to 8.4GB by means of
  the LBA standard), more disks (4 instead of 2) and for other mass
  storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
  ATA-4 and provides faster (and more CPU friendly) transfer modes
  than previous PIO (Programmed processor Input/Output) from previous
  ATA/IDE standards by means of fast DMA controllers.

  ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
  CD-ROM drives, similar in many respects to the SCSI protocol.

  SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
  designed in order to prevent data corruption and disk crash by
  detecting pre hardware failure conditions (heat, access time, and
  the like...). Disks built since June 1995 may follow this standard.
  The kernel itself don't manage this; however there are quite a
  number of user programs such as smart that can query the status of
  SMART parameters disk.

  If you want to compile this driver as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>. The module
  will be called ide.o.

  For further information, please read <file:Documentation/ide.txt>.

  If unsure, say Y.

CONFIG_DISCONTIGMEM
  Say Y to upport efficient handling of discontiguous physical memory,
  for architectures which are either NUMA (Non-Uniform Memory Access)
  or have huge holes in the physical address space for other reasons.
  See <file:Documentation/vm/numa> for more.

CONFIG_ISA
  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.

CONFIG_PCI
  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.linuxdoc.org/docs.html#howto>, contains valuable
  information about which PCI hardware does work under Linux and which
  doesn't.

CONFIG_PCI_INTEGRATOR
  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.linuxdoc.org/docs.html#howto>, contains valuable
  information about which PCI hardware does work under Linux and which
  doesn't.

CONFIG_PREEMPT
  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_MCA
  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_EISA
  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_HOTPLUG
  Say Y here if you want to plug devices into your computer while
  the system is running, and be able to use them quickly.  In many
  cases, the devices can likewise be unplugged at any time too.

  One well known example of this is PCMCIA- or PC-cards, credit-card
  size devices such as network cards, modems or hard drives which are
  plugged into slots found on all modern laptop computers.  Another
  example, used on modern desktops as well as laptops, is USB.

  Enable HOTPLUG and KMOD, and build a modular kernel.  Get agent
  software (at <http://linux-hotplug.sourceforge.net/>) and install it.
  Then your kernel will automatically call out to a user mode "policy
  agent" (/sbin/hotplug) to load modules and set up software needed
  to use devices as you hotplug them.

CONFIG_PCMCIA
  Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
  computer.  These are credit-card size devices such as network cards,
  modems or hard drives often used with laptops computers.  There are
  actually two varieties of these cards: the older 16 bit PCMCIA cards
  and the newer 32 bit CardBus cards.  If you want to use CardBus
  cards, you need to say Y here and also to "CardBus support" below.

  To use your PC-cards, you will need supporting software from David
  Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
  for location).  Please also read the PCMCIA-HOWTO, available from
  <http://www.linuxdoc.org/docs.html#howto>.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  When compiled this way, there will be modules called pcmcia_core.o
  and ds.o.  If you want to compile it as a module, say M here and
  read <file:Documentation/modules.txt>.

CONFIG_KCORE_ELF
  If you enabled support for /proc file system then the file
  /proc/kcore will contain the kernel core image. This can be used
  in gdb:

  $ cd /usr/src/linux ; gdb vmlinux /proc/kcore

  You have two choices here: ELF and A.OUT. Selecting ELF will make
  /proc/kcore appear in ELF core format as defined by the Executable
  and Linking Format specification. Selecting A.OUT will choose the
  old "a.out" format which may be necessary for some old versions
  of binutils or on some architectures.

  This is especially useful if you have compiled the kernel with the
  "-g" option to preserve debugging information. It is mainly used
  for examining kernel data structures on the live kernel so if you
  don't understand what this means or are not a kernel hacker, just
  leave it at its default value ELF.

CONFIG_KCORE_AOUT
  Not necessary unless you're using a very out-of-date binutils
  version.  You probably want KCORE_ELF.

CONFIG_BINFMT_ELF
  ELF (Executable and Linkable Format) is a format for libraries and
  executables used across different architectures and operating
  systems. Saying Y here will enable your kernel to run ELF binaries
  and enlarge it by about 13 KB. ELF support under Linux has now all
  but replaced the traditional Linux a.out formats (QMAGIC and ZMAGIC)
  because it is portable (this does *not* mean that you will be able
  to run executables from different architectures or operating systems
  however) and makes building run-time libraries very easy. Many new
  executables are distributed solely in ELF format. You definitely
  want to say Y here.

  Information about ELF is contained in the ELF HOWTO available from
  <http://www.linuxdoc.org/docs.html#howto>.

  If you find that after upgrading from Linux kernel 1.2 and saying Y
  here, you still can't run any ELF binaries (they just crash), then
  you'll have to install the newest ELF runtime libraries, including
  ld.so (check the file <file:Documentation/Changes> for location and
  latest version).

  If you want to compile this as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>.  The module
  will be called binfmt_elf.o. Saying M or N here is dangerous because
  some crucial programs on your system might be in ELF format.

CONFIG_BINFMT_AOUT
  A.out (Assembler.OUTput) is a set of formats for libraries and
  executables used in the earliest versions of UNIX. Linux used the
  a.out formats QMAGIC and ZMAGIC until they were replaced with the
  ELF format.

  As more and more programs are converted to ELF, the use for a.out
  will gradually diminish. If you disable this option it will reduce
  your kernel by one page. This is not much and by itself does not
  warrant removing support. However its removal is a good idea if you
  wish to ensure that absolutely none of your programs will use this
  older executable format. If you don't know what to answer at this
  point then answer Y. If someone told you "You need a kernel with
  QMAGIC support" then you'll have to say Y here. You may answer M to
  compile a.out support as a module and later load the module when you
  want to use a program or library in a.out format. The module will be
  called binfmt_aout.o. Saying M or N here is dangerous though,
  because some crucial programs on your system might still be in A.OUT
  format.

CONFIG_BINFMT_MISC
  If you say Y here, it will be possible to plug wrapper-driven binary
  formats into the kernel. You will like this especially when you use
  programs that need an interpreter to run like Java, Python or
  Emacs-Lisp. It's also useful if you often run DOS executables under
  the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO, available from
  <http://www.linuxdoc.org/docs.html#howto>). Once you have
  registered such a binary class with the kernel, you can start one of
  those programs simply by typing in its name at a shell prompt; Linux
  will automatically feed it to the correct interpreter.

  You can do other nice things, too. Read the file
  <file:Documentation/binfmt_misc.txt> to learn how to use this
  feature, and <file:Documentation/java.txt> for information about how
  to include Java support.

  You must say Y to "/proc file system support" (CONFIG_PROC_FS) to
  use this part of the kernel.

  You may say M here for module support and later load the module when
  you have use for it; the module is called binfmt_misc.o. If you
  don't know what to answer at this point, say Y.

CONFIG_VGA_CONSOLE
  Saying Y here will allow you to use Linux in text mode through a
  display that complies with the generic VGA standard. Virtually
  everyone wants that.

  The program SVGATextMode can be used to utilize SVGA video cards to
  their full potential in text mode. Download it from
  <ftp://ibiblio.org/pub/Linux/utils/console/>.

  Say Y.

CONFIG_ARCH_ANAKIN
  The Anakin is a StrongArm based SA110 - 2 DIN Vehicle Telematics Platform.
  64MB SDRAM - 4 Mb Flash - Compact Flash Interface - 1 MB VRAM

  On board peripherals:
        * Front display: 400x234 16 bit TFT touchscreen
        * External independent second screen interface
        * CAN controller SJA1000
        * USB host controller
        * 6 channel video codec with hardware overlay
        * Smartcard reader
        * IrDa

  Modules interfaced over the Multi Media Extension slots:
        * A communication card
                Wavecom GPRS modem
                uBlock GPS
                Bosch DAB module
        * An audio card ( 4 * 40W, AC97 Codec, I2S)

CONFIG_ARCH_CAMELOT
  This enables support for Altera's Excalibur XA10 development board.
  If you would like to build your kernel to run on one of these boards
  then you must say 'Y' here. Otherwise say 'N'

CONFIG_SCSI
  If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
  any other SCSI device under Linux, say Y and make sure that you know
  the name of your SCSI host adapter (the card inside your computer
  that "speaks" the SCSI protocol, also called SCSI controller),
  because you will be asked for it.

  You also need to say Y here if you want support for the parallel
  port version of the 100 MB IOMEGA ZIP drive.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called scsi_mod.o.  If you want to compile it as
  a module, say M here and read <file:Documentation/modules.txt> and
  <file:Documentation/scsi.txt>.  However, do not compile this as a
  module if your root file system (the one containing the directory /)
  is located on a SCSI device.

CONFIG_NETDEVICES
  You can say N here if you don't intend to connect your Linux box to
  any other computer at all or if all your connections will be over a
  telephone line with a modem either via UUCP (UUCP is a protocol to
  forward mail and news between unix hosts over telephone lines; read
  the UUCP-HOWTO, available from
  <http://www.linuxdoc.org/docs.html#howto>) or dialing up a shell
  account or a BBS, even using term (term is a program which gives you
  almost full Internet connectivity if you have a regular dial up
  shell account on some Internet connected Unix computer. Read
  <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>).

  You'll have to say Y if your computer contains a network card that
  you want to use under Linux (make sure you know its name because you
  will be asked for it and read the Ethernet-HOWTO (especially if you
  plan to use more than one network card under Linux)) or if you want
  to use SLIP (Serial Line Internet Protocol is the protocol used to
  send Internet traffic over telephone lines or null modem cables) or
  CSLIP (compressed SLIP) or PPP (Point to Point Protocol, a better
  and newer replacement for SLIP) or PLIP (Parallel Line Internet
  Protocol is mainly used to create a mini network by connecting the
  parallel ports of two local machines) or AX.25/KISS (protocol for
  sending Internet traffic over amateur radio links).

  Make sure to read the NET-3-HOWTO. Eventually, you will have to read
  Olaf Kirch's excellent and free book "Network Administrator's
  Guide", to be found in <http://www.linuxdoc.org/docs.html#guide>. If
  unsure, say Y.

CONFIG_ARM_THUMB
  Say Y if you want to have kernel support for ARM Thumb instructions,
  fault handlers, and system calls.

  The Thumb instruction set is a compressed form of the standard ARM
  instruction set resulting in smaller binaries at the expense of
  slightly less efficient code.

  If you don't know what this all is, saying Y is a safe choice.

CONFIG_PM
  "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.cs.utexas.edu/users/kharker/linux-laptop/> and the
  Battery Powered Linux mini-HOWTO, available from
  <http://www.linuxdoc.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_APM
  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.linuxdoc.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 ( = code which can be inserted in
  and removed from the running kernel whenever you want), say M here
  and read <file:Documentation/modules.txt>. The module will be called
  apm.o.

CONFIG_MAGIC_SYSRQ
  If you say Y here, you will have some control over the system even
  if the system crashes for example during kernel debugging (e.g., you
  will be able to flush the buffer cache to disk, reboot the system
  immediately or dump some status information). This is accomplished
  by pressing various keys while holding SysRq (Alt+PrintScreen). It
  also works on a serial console (on PC hardware at least), if you
  send a BREAK and then within 5 seconds a command keypress. The
  keys are documented in <file:Documentation/sysrq.txt>. Don't say Y
  unless you really know what this hack does.

CONFIG_ARCH_ARCA5K
  This selects what ARM system you wish to build the kernel for. It
  also selects to some extent the CPU type. If you are unsure what
  to set this option to, please consult any information supplied with
  your system.

CONFIG_ARCH_A5K
  Say Y here to to support the Acorn A5000.  Linux can support the
  internal IDE disk and CD-ROM interface, serial and parallel port,
  and the floppy drive.  Note that on some A5000s the floppy is
  plugged into the wrong socket on the motherboard.

CONFIG_ARCH_ARC
  The Acorn Archimedes was an personal computer based on an 8K ARM2
  processor, released in 1987.  It supported 512K of RAM and 2 800K
  floppy disks.  Picture and more detailed specifications at
  <http://www.computingmuseum.com/museum/archi.htm>.

CONFIG_ARCH_EBSA110

  The ARM610 is the successor to the ARM3 processor
  and was produced by VLSI Technology Inc.

  Say Y if you want support for the ARM610 processor.
  Otherwise, say N.

CONFIG_CPU_ARM710
  A 32-bit RISC microprocessor based on the ARM7 processor core
  designed by Advanced RISC Machines Ltd. The ARM710 is the
  successor to the ARM610 processor. It was released in
  July 1994 by VLSI Technology Inc.

  Say Y if you want support for the ARM710 processor.
  Otherwise, say N.

CONFIG_CPU_ARM720T
  A 32-bit RISC processor with 8kByte Cache, Write Buffer and
  MMU built around an ARM7TDMI core.

  Say Y if you want support for the ARM720T processor.
  Otherwise, say N.

CONFIG_CPU_ARM920T
  The ARM920T is licensed to be produced by numerous vendors,
  and is used in the Maverick EP9312.  More information at
  <http://linuxdevices.com/products/PD2382866068.html>.

  Say Y if you want support for the ARM920T processor.
  Otherwise, say N.

CONFIG_CPU_ARM922T
  The ARM922T is a version of the ARM920T, but with smaller
  instruction and data caches. It is used in Altera's
  Excalibur XA device family.

  Say Y if you want support for the ARM922T processor.
  Otherwise, say N.

CONFIG_CPU_ARM1020
  The ARM1020 is the cached version of the ARM10 processor,
  with an addition of a floating-point unit.

  Say Y if you want support for the ARM1020 processor.
  Otherwise, say N.

CONFIG_CPU_SA110
  The Intel StrongARM(R) SA-110 is a 32-bit microprocessor and
  is available at five speeds ranging from 100 MHz to 233 MHz.
  More information is available at
  <http://developer.intel.com/design/strong/sa110.htm>.

  Say Y if you want support for the SA-110 processor.
  Otherwise, say N.

CONFIG_CPU_ICACHE_DISABLE
  Say Y here to disable the processor instruction cache. Unless
  you have a reason not to or are unsure, say N.

CONFIG_CPU_DCACHE_DISABLE
  Say Y here to disable the processor data cache. Unless
  you have a reason not to or are unsure, say N.

CONFIG_CPU_DCACHE_WRITETHROUGH
  Say Y here to use the data cache in writethough mode. Unless you
  specifically require this or are unsure, say N.

CONFIG_CPU_CACHE_ROUND_ROBIN
  Say Y here to use the predictable round-robin cache replacement
  policy.  Unless you specifically require this or are unsure, say N.

CONFIG_CPU_BPREDICT_DISABLE
  Say Y here to disable branch prediction.  If unsure, say N.

CONFIG_FPE_NWFPE
  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.

  It is also possible to say M to build the emulator as a module
  (nwfpe.o) or indeed to leave it out altogether. However, unless you
  know what you are doing this can easily render your machine
  unbootable. Saying Y is the safe option.

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

CONFIG_FPE_FASTFPE
  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.

  It is also possible to say M to build the emulator as a module
  (fastfpe.o).  But keep in mind that you should only load the FP
  emulator early in the bootup.  You should never change from NWFPE to
  FASTFPE or vice versa in an active system!

CONFIG_DEBUG_ERRORS
  This option controls verbose debugging information which can be
  printed when the kernel detects an internal error. This debugging
  information is useful to kernel hackers when tracking down problems,
  but mostly meaningless to other people. It's safe to say Y unless
  you are concerned with the code size or don't want to see these
  messages.

CONFIG_NO_FRAME_POINTER
  If you say Y here, the resulting kernel will be slightly smaller and
  faster. However, when a problem occurs with the kernel, the
  information that is reported is severely limited. Most people
  should say N here.

CONFIG_DEBUG_USER
  When a user program crashes due to an exception, the kernel can
  print a brief message explaining what the problem was. This is
  sometimes helpful for debugging but serves no purpose on a
  production system. Most people should say N here.

CONFIG_DEBUG_INFO
  Say Y here to include source-level debugging information in the
  `vmlinux' binary image. This is handy if you want to use gdb or
  addr2line to debug the kernel. It has no impact on the in-memory
  footprint of the running kernel but it can increase the amount of
  time and disk space needed for compilation of the kernel. If in
  doubt say N.

CONFIG_DEBUG_LL
  Say Y here to include definitions of printascii, printchar, printhex
  in the kernel.  This is helpful if you are debugging code that
  executes before the console is initialized.

CONFIG_DEBUG_DC21285_PORT
  Say Y here if you want the debug print routines to direct their
  output to the serial port in the DC21285 (Footbridge). Saying N
  will cause the debug messages to appear on the first 16550
  serial port.

CONFIG_DEBUG_CLPS711X_UART2
  Say Y here if you want the debug print routines to direct their
  output to the second serial port on these devices.  Saying N will
  cause the debug messages to appear on the first serial port.

CONFIG_NO_PGT_CACHE
  Normally the kernel maintains a `quicklist' of preallocated
  pagetable structures in order to increase performance. On machines
  with very few pages this may however be a loss. Say Y here to
  disable the pgtable cache.

CONFIG_ARTHUR
  Say Y here to include the kernel code necessary if you want to run
  Acorn RISC OS/Arthur binaries under Linux. This code is still very
  experimental; if this sounds frightening, say N and sleep in peace.
  You can also say M here to compile this support as a module (which
  will be called arthur.o).

CONFIG_CMDLINE
  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_ALIGNMENT_TRAP
  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.

CONFIG_DEBUG_KERNEL
  Say Y here if you are developing drivers or trying to debug and
  identify kernel problems.

CONFIG_DEBUG_SLAB
  Say Y here to have the kernel do limited verification on memory
  allocation as well as poisoning memory on free to catch use of freed
  memory.

CONFIG_DEBUG_SPINLOCK
  Say Y here and build SMP to catch missing spinlock initialization
  and certain other kinds of spinlock errors commonly made.  This is
  best used in conjunction with the NMI watchdog so that spinlock
  deadlocks are also debuggable.

CONFIG_DEBUG_BUGVERBOSE
  Say Y here to make BUG() panics output the file name and line number
  of the BUG call as well as the EIP and oops trace.  This aids
  debugging but costs about 70-100K of memory.

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

CONFIG_ZBOOT_ROM_BSS
  The base address of 64KiB of read/write memory, which must be available
  while the decompressor is running.  Unless you have special requirements,
  you should not change this value.

CONFIG_CPU_FREQ
  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_ARCH_EDB7211
  Say Y here if you intend to run this kernel on a Cirrus Logic EDB-7211
  evaluation board.

CONFIG_SA1100_H3100
  Say Y here if you intend to run this kernel on the Compaq iPAQ
  H3100 handheld computer.  Information about this machine and the

  Say Y here if you intend to run this kernel on the Compaq iPAQ H3800
  series handheld computer.  Information about this machine and the
  Linux port to this machine can be found at:

  <http://www.handhelds.org/Compaq/index.html#iPAQ_H3800>
  <http://www.compaq.com/products/handhelds/pocketpc/>

CONFIG_H3600_SLEEVE
  Choose this option to enable support for extension packs (sleeves)
  for the Compaq iPAQ H3XXX series of handheld computers.  This option
  is required for the CF, PCMCIA, Bluetooth and GSM/GPRS extension
  packs.

  1110-based SBC, used primarily in assistance products for the
  visually impaired.  The company is now Freedom Scientific, with
  a website at <http://www.freedomscientific.com/index.html>. The
  Sherman product, however, appears to have been discontinued.

CONFIG_SA1100_PT_SYSTEM3
   Say Y here if you intend to build a kernel suitable to run on
   a Pruftechnik Digital Board. For more information see
   <http://www.pruftechnik.com>

CONFIG_CPU_ARM926T
  This is a variant of the ARM920.  It has slightly different
  instruction sequences for cache and TLB operations.  Curiously,
  there is no documentation on it at the ARM corporate website.

  Say Y if you want support for the ARM926T processor.
  Otherwise, say N.

CONFIG_SA1100_JORNADA720
  Say Y here if you want to build a kernel for the HP Jornada 720
  handheld computer.  See <http://www.hp.com/jornada/products/720>
  for details.

CONFIG_SA1100_OMNIMETER
  Say Y here if you are using the inhand electronics OmniMeter.  See
  <http://www.inhandelectronics.com/html/omni1.html> for details.

CONFIG_SA1100_SIMPAD
  The SIEMENS webpad SIMpad is based on the StrongARM 1110. There
  are two different versions CL4 and SL4. CL4 has 32MB RAM and 16MB
  FLASH. The SL4 version got 64 MB RAM and 32 MB FLASH and a
  PCMCIA-Slot. The version for the Germany Telecom (DTAG) is the same
  like CL4 in additional it has a PCMCIA-Slot. For more information
  visit <http://www.my-siemens.com or www.siemens.ch>.

CONFIG_ARCH_CDB89712
  This is an evaluation board from Cirrus for the CS89712 processor.
  The board includes 2 serial ports, Ethernet, IRDA, and expansion
  headers.  It comes with 16 MB SDRAM and 8 MB flash ROM.

CONFIG_ARCH_AUTCPU12
  Say Y if you intend to run the kernel on the autronix autcpu12
  board. This board is based on a Cirrus Logic CS89712.

CONFIG_EP72XX_ROM_BOOT
  If you say Y here, your CLPS711x-based kernel will use the bootstrap
  mode memory map instead of the normal memory map.

  Processors derived from the Cirrus CLPS-711X core support two boot
  modes.  Normal mode boots from the external memory device at CS0.
  Bootstrap mode rearranges parts of the memory map, placing an
  internal 128 byte bootstrap ROM at CS0.  This option performs the
  address map changes required to support booting in this mode.

  You almost surely want to say N here.
