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

[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

I think that you use my patchset. It is true?

Almost. I used it as base but modified it quite a bit. There is almost no 
difference between IXP465 and IXP425 anymore (except header files), no 
lowlevel-init.S anymore and correct CPU info display.

BTW: ixdp425_config, ixdpg425_config and pdnb3_config are broken if 
IxNpeMicrocode.o is not present

Ok, It was Walfgang ask to my version, but I don't have spare time to 
work on
it.

Here are my patches. Maybe you want to test them. I didn't use or update 
the ixdp465 but you can use the sidewinder_config as starting point.
Order is:
ixp425_rework.patch
ixp465.patch
npe_less_fw.patch
sidewinder.patch

I see only the ixp465.patch.
Some comments:
- remove c++ comment
- i prefer sdram controller inizialization in board specific part

Clean up the code of print_cpuinfo.

I can't comment anymore because your patch is not inlined in the email

???
The mail included all 4 patches.

> Some comments:

Ok.

> - i prefer sdram controller inizialization in board specific part

I don't because that will be 99,999% the same code for all IXP46x boards. 
That's avoidable code duplication.
And the SDRAM initialisation is specified by intel to very specific steps, 
anyway. All important differences can be (and are) expressed as variables. 
What would you do differently?
If you do it completely different, add a define like CFG_CUSTOM_DRAM_INIT 
that disables the generic code and forces you to add your own.

> Clean up the code of print_cpuinfo.

What do you mean?

> I can't comment anymore because your patch is not inlined in the email

Sorry, I didn't find out how to inline patches with Lotus Notes, yet. :-(
Yes, that software really sucks :-(

To work around the limitation of this MUA, the patches are available at
http://www.hendrik-sattler.de/patches/ixp465/

Note: these patches are for u-boot 1.3.4! Maybe some incompatible changes 
that followed that version.

Dear h.sattler at erhardt-leimer.com,

Please STOP prepending the non-standard "Antwort: " to  the  subject,
as this essentially makes the Subjkect line useless. Please make sure
to use a RCF-conformant MUA to compose your messages.

In message <OF8F1EBCA2.E6BA03A3-ONC12574DC.003A8028-C12574DC.003A7339@erhardt-leimer.com> you wrote:

It doesn;t work like that. Patches have to be posted on the mailing
list, or they will be ignored.

> Note: these patches are for u-boot 1.3.4! Maybe some incompatible changes 
> that followed that version.

Then please rebase your patches against top of tree, and send them to
the ML.

Thanks.

In theory, there is no difference between  theory  and  practice.  In
practice, however, there is.
