Subject[PATCH 1/5] ARM: remove ixp23xx and ixp2000 platforms
Date
From: Rob Herring <rob.herring@calxeda.com>

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 rest of the patch is just deleted files and too big to get thru the
