[kernel-2.6.19]Marvell GT-64260 and Ethernet

Hi all,
I'm porting a Linux kernel 2.6.19 on a PowerPC 750 FX board.
My Linux runs completely except for Ethernet. I don't find any Ethernet
driver for my bridge. Do you know if there is an Ethernet driver for the
Marvell GT-64260 bridge for PowerPC processor. I found a GT-64260 ethernet
driver in the kernel 2.4.34 for MIPS processor, will it be possible to port
it in a 2.6 kernel?
Thanks for you help.

Isn't the ethernet the same on the 64260, 64360, 64460?

There's definitely a driver for 6436x and above..

I believe that Steve Hill <sjhill@realitydiluted.com> has patched
the mv643xx_eth driver to work with the 64260 and plans to submit
the patches.

I just try it, it doesn't work, I receive without end the message:
mv643xx PHY read timeout, port 0

That's means the patch isn't yet ready?
I will try to contact him.

It's nevertheless odd, I read about a file named gt64260_eth.c during my
search on the internet.But I wasn't able to find it :(.

Thanks for you help

It was in the (now obsolete) linuxppc_2_4_devel kernel.  I can send
you a copy, but a merged mv64x60 driver will be much better.

It probably means you don't something set up for whatever PHY you're
using.

A good idea.

There was one for 2.4 that was in the ppc devel tree but it never went
mainline.  Hopefully, Steve can help you from here.

You need to check the phy address and the type of the PHY used.
If it is not there/or supported, you may want to include them.

There was some work done back in the early 2.6 timeframe to make a unified 
360/260 driver. I worked on in a while ago (2+ years) I think the reason you 
don't see it in the tree, is because we all stopped using the 260 and went to 
the 360 as fast as possible. 
gt64260_eth.c ill not jus work. A lot of work (Mark Greer etc) was done in 
refactoring most of the Marvell support from 2.4->2.6. You might get away 
with setting up the platfrom correctly for the 260. Check out the ppc/syslib 
directory. You might find some clues there,


Thanks
