[U-Boot] PATCH: IXP465 support and some IXP4xx rework, Sidewinder board support

[h.sattler at erhardt-leimer.com]

Hi,

on the matter of getting u-boot work with the ADI Sidewinder Reference 
Platform, I found the previously posted patches and used them as starting 
point for my own patch set.
The Sidewinder board works with this patch, including ECC (optional).

There is a minimum set of ifdefs in cpu/ixp/start.S and no board-specific 
low-level.S and thus no endless code-duplication. The
SDRAM parameters are handled by configuration definitions.
The ixp425.h and ixp465.h header files should be merged but that can 
follow in a different patch, possibly renaming the defines and fixing all 
board specific code.
The new initialisation routine was also tested on an IXP425, it really 
works on both.

The npe_less_fw.patch allows to have NPE-C firmware and still use NPE-B. 
There is no need to load firmware to NPE-C if you are not going to use it.

This work was done for Erhardt+Leimer GmbH.


Note:
I hope this can be merged, however, your description at 
http://www.denx.de/wiki/U-Boot/Patches makes me worry. I can only use 
Lotus Notes and that's a bit limited. No, I cannot use another MUA from 
here, really! If you can accept them at attachments (patches with 
description header, diff index and Signed-off-by line, I use quilt 
locallly).

Sincerly,

Hendrik Sattler
