860P FEC and fec driver from 2.3?

860P FEC and fec driver from 2.3?

[Gessner, Matt]

Do this work?  I've got someone here who's got the LXT970 PHY
and the thing doesn't work with the driver from 2.3 I've got.
Has it changed?  I don't have access to the bitkeeper tree,
so I'm flying a BIT blind here... Can anyone make any recommendations,
please?

Thanks,

Matt

There have been some changes through the course of 2.3 and 2.4.
I think Wolfgang Denk finally fixed the FEC driver so it can be
use in 2.4.  Some of the software modifications were driver
interface related, and I made a couple because the MII pin
configuration changed with > Rev. C of the parts.

The 860P certainly works, I use one almost every day for some
kind of network activity.

It probably does not work with 2.3.x code; but then  -  I  never  got
lucky with any 2.3 code :-(

Right. See our version of the sources in
ftp://ftp.denx.de/pub/LinuxPPC/usr/src

Works fine in a couple of systems based on 860T and 860P  CPUs,  with
Level One 970 and 9880 and similar PHY's.

If your hardware does autoconfiguration you can omit most of the  PHY
recognistion  stuff;  otherwise enable it, but then you must assign a
PHY interrupt.

Me too (in an ISDN router).
