booting linux on powerpc 405

[[EMAIL PROTECTED]]

Hello.I am not an expert regarding this board but the output below looks like 
it is something wrong with root fs-like you use a rfs built for another arch. 
Just a pure guess..

Maybe you can send me a copy of your patch so we can  include  it  in

[OT?] recommendations for a small footprint DB for PPC system?

[Robert P. J. Day]

  any recommendations for a small, relational database that can be
cross-compiled with ELDK 3.1.1 for a PPC system?  it's not going to be
holding a lot of records (about 1000, more or less), and will be
initialized and loaded at system boot time, at which point the
majority of operations will be read, with only occasional writes.

  thoughts?

[PATCH] I2C-MPC: Remove OCP device model support

[Kumar Gala]

All consumers of the driver MPC10x, MPC52xx, MPC824x, MPC83xx,
and MPC85xx are all using platform devices.  We can get ride of
the dead code to support using this driver with the old OCP based
model

[PATCH] ppc32: Remove FSL OCP support

Support for the OCP device model on Freescale (FSL) PPC's is no
longer used.  All FSL PPC's that were using OCP have be converted
to using the platform device model.

[PATCH] ppc32: Add support for Freescale e200 (Book-E) core

[Kumar Gala]

The e200 core is a Book-E core (similar to e500) that has a unified L1
cache and is not cache coherent on the bus.  The e200 core also adds a
separate exception level for debug exceptions.  Part of this patch helps 
to cleanup a few cases that are true for all Freescale Book-E parts, not 
just e500.

[PATCH] ppc32: Check return of ppc_sys_get_pdata before accessing pointer

[Kumar Gala]

Ensure that the returned pointer from ppc_sys_get_pdata is not
NULL before we start using it.  This handles any cases where we
have variants of processors on the same board with different
functionality.

isp1362 usb driver

[Jianliang Lu]

Hi Jordan,
yes I would be really, really gratefully if you could send me the 
source.

The adsl modem we are using is a eagle chipset modem, based on 
eagle-usb project. The modem could be Sagem or aethra on ADI eagle 
chipset.

Best regards,
Jianliang Lu

isp1362 usb driver

[Jianliang Lu]

Hi,
the device is a adsl modem, it works correctly in other linux 
systems with kernel 2.4.2x. The problem is that the isp1362 driver 
seems that supports only isochronous endpoints. We are 
implementing the code to support also control/bulk/interrupt 
endpoints.

Regards,
Jianliang Lu

I had similar issues with control/bulk/interrupt endpoints with
the ISP1362 host controller driver from DENX.  I went ahead and added
better support for control/bulk/interrupt endpoints.  I could send you a
copy of the source if you like.  The driver is being used on an MPC880,
with the 2.4.21 kernel.  Also, what ADSL modem are using?  We are
looking into a solution requiring an ADSL modem and the one you are
using may be a good solution for us also.
