ARM: remove ixp23xx and ixp2000 platforms



ixp2xxx platforms have had no real changes since ~2006 and the maintainer
has said on irc that they can be removed:

13:05 < nico> do you still care about ixp2000?
13:22 < lennert> not really, no
13:58 < nico> do you think we could remove it from the kernel tree?
14:01 < lennert> go for it, and remove ixp23xx too while you're at it

Removing will help simplify ARM consolidation in general and PCI re-work
specifically.

		Release Notes for Linux on Intel's IXP2000 Network Processor

		Maintained by Deepak Saxena <dsaxena@plexity.net>
		-------------------------------------------------------------------------

		1. Overview

		Intel's IXP2000 family of NPUs (IXP2400, IXP2800, IXP2850) is designed
		for high-performance network applications such high-availability
		telecom systems. In addition to an XScale core, it contains up to 8
		"MicroEngines" that run special code, several high-end networking
		interfaces (UTOPIA, SPI, etc), a PCI host bridge, one serial port,
		flash interface, and some other odds and ends. For more information, see:

		http://developer.intel.com

		2. Linux Support

		Linux currently supports the following features on the IXP2000 NPUs:

		- On-chip serial
		- PCI
		- Flash (MTD/JFFS2)
		- I2C through GPIO
		- Timers (watchdog, OS)

		That is about all we can support under Linux ATM b/c the core networking
		components of the chip are accessed via Intel's closed source SDK.
		Please contact Intel directly on issues with using those. There is
		also a mailing list run by some folks at Princeton University that might
		be of help: https://lists.cs.princeton.edu/mailman/listinfo/ixp2xxx

		WHATEVER YOU DO, DO NOT POST EMAIL TO THE LINUX-ARM OR LINUX-ARM-KERNEL
		MAILING LISTS REGARDING THE INTEL SDK.

		3. Supported Platforms

		- Intel IXDP2400 Reference Platform
		- Intel IXDP2800 Reference Platform
		- Intel IXDP2401 Reference Platform
		- Intel IXDP2801 Reference Platform
		- RadiSys ENP-2611

		4. Usage Notes

		- The IXP2000 platforms usually have rather complex PCI bus topologies
		with large memory space requirements. In addition, b/c of the way the
		Intel SDK is designed, devices are enumerated in a very specific
		way. B/c of this this, we use "pci=firmware" option in the kernel
		command line so that we do not re-enumerate the bus.

		- IXDP2x01 systems have variable clock tick rates that we cannot determine
		via HW registers. The "ixdp2x01_clk=XXX" cmd line options allow you
		to pass the clock rate to the board port.

		5. Thanks

		The IXP2000 work has been funded by Intel Corp. and MontaVista Software, Inc.

		The following people have contributed patches/comments/etc:

		Naeem F. Afzal
		Lennert Buytenhek
		Jeffrey Daly
