From c65f2abf54a6d07260f1fa64773154e1d7047961 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 30 Mar 2012 23:37:53 -0500 Subject: 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.

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.
