Re: fast ethernet LXT972A support

In message [off-list ref] you wrote:

I noticed that only LXT970 and 971 are supported in the lastest kernel
distribution from DENX. But the comments in fec.c say "includes support
for following PHYs: QS6612, LXT970, LXT971/2". Does it mean that LXT972
can use 971's driver? If not, basically what kind of modification is
needed? Thanks.

Ummm.... you must be looking in the wrong place; our  kernel  version
supports  AMD79C874, LXT970, LXT971, QS6612, DP83843, and DP83846A on
MPC8xx processors, and AMD79C873, LXT970, LXT971, QS6612  on  MPC8260
processors.

The software required `Windows 95 or better', so I installed Linux.

Well, the first several lines of comments says that. ;)

Well, the version I got is linux-2.4.4-08-09. And I'm sure there are no
DP83843 and DP83846A support. So you must have made progress in
supporting new PHYs. :) The file I'm looking at is arch/ppc/8xx_io/fec.c.
