+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_PAGESIZE_16
+  Say Y here if your Archimedes or A5000 system has only 2MB of
+  memory, otherwise say N.  The resulting kernel will not run on a
+  machine with 4MB of memory.

+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_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_CEIVA
+  Say Y here if you intend to run this kernel on the Ceiva/Polaroid
+  PhotoMax Digital Picture Frame.
+
+CONFIG_ARCH_EDB7211
+  Say Y here if you intend to run this kernel on a Cirrus Logic EDB-7211
+  evaluation board.
+
+CONFIG_ARCH_P720T
+  Say Y here if you intend to run this kernel on the ARM Prospector
+  720T.
+
+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.

+CONFIG_SA1100_SHERMAN
+  Say Y here to support the Blazie Engineering `Sherman' StrongARM
+  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_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_SA1100_PFS168
+  The Radisys Corp. PFS-168 (aka Tulsa) is an Intel® StrongArm® SA-1110 based
+  computer which includes the SA-1111 Microprocessor Companion Chip and other
+  custom I/O designed to add connectivity and multimedia features for vending
+  and business machine applications. Say Y here if you require support for
+  this target.
+
+CONFIG_SA1100_VICTOR
+  Say Y here if you are using a Visu Aide Intel(R) StrongARM(R)
+  SA-1100 based Victor Digital Talking Book Reader.  See
+  <http://www.visuaide.com/pagevictor.en.html> for information on
+  this system.
+
+CONFIG_SA1100_XP860
+  :: Config help missing ::
+  :: 06 August 2002 ::
+
+CONFIG_SA1100_YOPY
+  Say Y here to support the Yopy PDA.  Product information at
+  <http://www.yopy.com/>.  See Documentation/arm/SA110/Yopy
+  for more.
+
+CONFIG_SA1100_STORK
+  Say Y here if you intend to run this kernel on the Stork
