ixp4xx, ixp425-eth: add Intel Access Library 2.0, ethernet driver 1.4

NOTE: to use these you must pin ixp4xx-csr, ixp-oxal and ixp400-eth.
The name of the ethernet driver changes with this commit - it is now
ixp400-eth, not ixp425-eth - changes are required in systems which need
to use the ethernet driver and these changes are *not* in this commit.
The things to change are the image (which must now depend on ixp400-eth)
and any modprobe.conf (which, at least in NSLU2 - openslug-init - aliases
eth0 as ixp4??-eth).

++This file describes a patch to use version 1.5 of the Intel Ixp4XX
++Access Library with Linux 2.6 kernels.
++
++Authors/History
++---------------
++
++This patch consists of the changes made by Marc Singer for use of
++version 1.5 of the library with the APEX bootloader, and a patch made
++by Robin Farine and Tom Winkler for use of version 1.4 of the library
++with Linux-2.6 kernels. These changes were merged together by Hannes
++Reich.
++
++Both patches are incorporated in their entirety, with the exception of
++some tweaks to sleep times in the ethAcc code and modifications to
++the code in src/codelets/usb/ from the Robin Farine / Tom Winkler
++patch.
++
++Status
++------
++
++This code has been tested on a Linksys NSLU2. It works in big-endian
++mode, performance seems around 10% faster than 1.4.
++
++The code does not work in little-endian mode. It appears as though the
++hardware is initialised correctly, but packet receive / transmit done
++callbacks are never called.
++
++Licence Information
++-------------------
++
++The patch is licenced under the same conditions as the original Access
++Library 1.5 (INTEL SOFTWARE LICENSE AGREEMENT). The full text of the
++licence can be downloaded from:
++http://www.intel.com/design/network/swsup/np_sla/ixp400.htm
++
++The patch is free, unsupported and the authors make no warranties.
++Use it at your own risk, do with it as you see fit so long as you do
++not violate the original licence agreement.
++
++The authors permit derivative works based upon the patch.
++
++References
++----------
++
++The version 1.4 patch by Robin Farine and Tom Winkler is available from
++http://www.wnk.at/ixp400_accesslib_kernel26/data/patch_accesslib_kernel26_20040811.diff
++
++The version 1.5 patch by Marc Singer is at
++http://wiki.buici.com/bin/view/Main/IXPAccessLibrary
