We have the OSELAS.BSP patch stack for the PCM030 working ontop of
Linus' git. It still uses an older version of the Bestcom patches, so if
you do some work in that area, please keep me informed about your
progress.

What is the best way to proceed? I need to be on current git since we
are integrating a wireless driver that is tracking current git and the
mac80211 work.

I have Phytec (pcm030) and Efika hardware but I don't have a 5200lite.
Our prototype hardware uses the pcm030 module on a custom baseboard.

The best thing for me would be to get a FEC driver merged. That is the
largest piece of code  that is floating around. Getting that merged
would give me a stable base to build future patches on.

I'd also like to get support for the pcm030 (minus real-time) merged.
That isn't a lot of code once FEC is in the kernel.

Domen has posted this driver "[RFC PATCH v0.1] net driver: mpc52xx
fec". I can work on breaking that up, but I don't have a 5200lite so I
will have to port to pcm030. I don't want to start on this if someone
else is already doing it.

Sylvain's bestcomm patches need be cleaned up and resubmitted before
the next merge window opens.  AFAIK, the code is pretty much ready,
and all the comments have been addressed.  All that is required is the
final push to tidy the patchset and post to the list one more time.
Sylvain said that he was going to get this done last weekend, but I
haven't heard back from him yet.

Sylvain, if you need help, please let me know.  I'll happily take on
the last bit of tidy work if that's what is needed to be finished
before the merge window.  (And it needs to be ready *before*, not
during if I'm judging the prevailing winds correctly).

Is a version of this patch set that has been rebased to current git
available? If I have a starting point I can begin working on the
pcm030 support. pcm030 already works, it is just out of tree.

I think these patches are "latest":
http://www.246tnt.com/mpc52xx/dev_full/
Applying them to -git should not be a problem, I don't remember anything
tricky, but if you have problems, I can send you patches agains mainline.

BTW. I posted FEC patch v2, which will hopefully be merged.

I just booted your code successfully on current Linus git with a Phytec pcm030.

There is a timeout issue that is probably related to the specific
Ethernet PHY chip used on the pcm030. I'm looking into it now.
