Not sure, no. Looking at "xconfig", I don't see an option for it. A
colleague said it did.

We've used IDE (for a DVD-ROM) using the Denx kernel. This didn't have
DMA suppport, but Freescale gave us a derivate kernel that it, which
seemed to work well. They said they were going to push this up through
Denx into the main kernel. Didn't they bother to do this?

That'd be great.

The kernel on our CVS server does support DMA - at least to the lavel
that is available with the current IDE driver and microcode.

No it doesn't. Or it's very well hidden ;)
But If you do write it, patches are welcomed.

I guess they mean push it to Denx kernel which IS the main 2.4 kernel 
for MPC5200.
No new platform support will be accepted for 2.4 now. And freescale probably
won't write driver for the tree I maintain since I'm not using the 
official BestComm API.

That could save a lot of time, but is this kernel 2.4-based? The docs
there imply that (buildling a kernel natively section references paths
with 2_4 in them).

We already have a 2.4-based MontaVista, but we're trying to get a 2.6
kernel up and running with NPTL to compare the pthreads performance
differences...

Thanks for the pointer though.

Yes, it is.

You can probably use  the  2.4  kernel  for  installation  (or  -  as
mentioned  before  -  just use another PPC box and transfewr the disk
drive).

MPC5200 kernel with IDE *and* FEC?

[Stephen Warren]

I looked at the 2.6.11 kernel.org kernel, and it has MPC5200 IDE
support, but apparently no FEC driver support.

Sylvain's kernel has FEC, but no IDE support.

I don't suppose anyone had any patches hidden away to add one of the
missing pieces to either of these kernels?

By the way, to the people who mentioned using Debian and Gentoo on the
MPC5200, are there any web-sites that have info on how to do this
(toolchain and/or distro)? I haven't managed to find anything remotely
detailed on cross-building either of these distros. But I'll probably
just do it from scratch now I have NPTL-aware toolchain:-)

Are you sure it has MPC5200 IDE support?  I have yet to see reliable
5200 IDE support and haven't seen a 5200 IDE driver for 2.6 at all.

I did the FEC driver in Sylvain's tree.  He has promised to push
it to kernel.org RSN.

You don't have to cross-build anything; you can just use the existing
ISO images for installation. For Debian Woody you can find a detailed
description   (thanks   to    bernhard    Kuhn    for    this!)    at
http://www.denx.de/twiki/bin/view/DULG/DebianOnPowerpcInstallationHowto

In the meantime we swithched to using Ubuntu Linux on the  5200,  but
here  installation  is  a  bit  more  complicated as you will have to
twiddle with  the  installation  ramdisk  image,  and  later  perform
certain  steps  manually. It's probably easier to copy the filesystem
from a "real" PowerPC system ;-)
