We tried. We really tried.

David even posted on this list to get feedback  from  the  community.
But I haven't seen a single reply on the mailing lists.
So? Repost. I miss stuff the first time around a lot of times
myself [this is not to indicate that I would necessarily comment
on 5200 stuff, just an example].
Please don't blame _us_ that the 5xxx code was not accepted  for  the
public trees.

This is really not fair!!!
Fair? Of course the community isn't fair. It's fickle and often
concerned only with its own current projects. Persistence really
helps when one wants something to be in the trees. Frankly, I'm
surprised that this isn't a top priority for Freescale. Maintaining
code in the kernel.org trees is far more efficient than when it
bit rots in some other tree. It also makes the support for Freescale's
silicon available to a wider audience.  I think that has got to be
high on their list.

Just to add fuel to the fire, I'll note that others are able to
appear on #mklinux and work out the issues in real-time with the
folks there. is often more desirable and productive. It's also often
the only way to get Paul's attention. Oh, and FWIW, the folks working
hard on 8xx and 85xx acceptance do manage to do this.

I'm glad I don't give up as easy. It took me a while to get core OCP/4xx
in linux-2.5. :)

Yes, and the outcome was we made a linux-2.4-mpc5xxx tree, tried to get
comments, did so, and it was rejected for being too ugly for kernel.org
at the time, IIRC.

And this time do it against 2.6.  Even if 2.4 wasn't necessarily frozen
at the time we first tried, it is now.

Actually I got some patch to support MPC5200 ( and only this one, no
mgt5100 stuff ) for 2.6
It only supports booting, serial console and i2c. Not much but could
that be put in official tree if I submit it ? Or does it need to
support  more than that to worth inclusion.
So that at least if someone tries to implement more ( I'll resume my
work on it in a few weeks ), it has a base already in official tree.
