MPC5200 and Bestcomm

MPC5200 and Bestcomm

[Jon Smirl]

We're starting a new MPC5200 project and I'm trying to track down the
best kernel to start from. Is Sylvain's tree at
http://www.246tnt.com/mpc52xx/ a good place to start? The git URLs
from the web page don't work. Everything 5200 related in the trees at
Secret Labs already appears to be merged.

Most of this work also appears to be in the Open Embedded tree's Ekifa
support. Is that a better place to start?

I need to get multiple I2S ports running with DMA.

It might be.  The major problem with MPC5200 is the Ethernet driver.
I believe both Domen and Sylvain have been working on drivers suitable
for arch/powerpc inclusion.

We have integrated FEC code floating around into DENX Linux 2.6 tree,
and have it working on several boards in the arch/powerpc context.

It might be worthwhile to check out
git://www.denx.de/git/linux-2.6-denx.git#linux-2.6-denx

[Matt Sealey]

The current (2.6.22) patchset for the Efika is being held here for
the moment; http://dev.gentoo.org/~nixnut/efika/

That's everything you 'really need' and it's probably the same as
this patch list.

However practically none of it is mainline-worthy at the moment,
Sylvain has detailed too many things he thinks is wrong with it.

I'm having a go with the new ethernet driver patch right now (a
customer asked me for a prebuilt kernel..) so I can get on with
testing that. The most important ones for rewrites besides that
are the AC97 driver (which is a little.. sparse) and actually
using the ATA task.

I'll put in a decent request here for any work on this subject to
please at least attempt to retrieve the tasks from the Efika
firmware rather than replacing them in Linux gratuituously.
I understand this doesn't help the Lite5200 guys.. but.. pretty
please with a cherry on top? :]

We're making an open device with all software being replaceable. I
already have u-boot. Is there a free open firmware option? Which is
the recommended path?

Matt, I'll buy some Efikas as soon as you're selling them again.,
