config ARM
	bool
	default y
	help
	  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 MMU
	bool
	default y

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.

	  parallel port.

	  L7200 Software Development Board which uses an ARM720T processor.
	  Information on this board can be obtained at:

	  <http://www.linkupsys.com/>

	  If you have any questions or comments about the Linux kernel port
	  to this board, send e-mail to [e-mail].

	  Samsung S3C2410X CPU based systems, such as the Simtec Electronics
	  BAST (http://www.simtec.co.uk/products/EB110ITX/), the IPAQ 1940 or
	  the Samsung SMDK2410 development board (and derviatives).

config ARCH_LH7A40X
	bool "Sharp LH7A40X"
	help
	  Say Y here for systems based on one of the Sharp LH7A40X
	  System on a Chip processors.  These CPUs include an ARM922T
	  core with a wide array of integrated devices for
	  hand-held and low-power applications.
