MPC5200/Lite5200 and ethernet

[Esben Nielsen]

How do I turn on the in chip FEC ethernet controller in MPC5200 in the
stock 2.6.12-rc6 kernel? Do I need an extra patch?

But, since bestcomm still not converted to platform_bus/ppc_sys model,
it will not be included in vanilla 2.6.12 kernel.

I managed to get something out of the bitkeeper tree referred to from
http://www.246tnt.com/mpc52xx/
It seems to be based on 2.6.10-rc2 right now - good enough for now.

Is that really the latest version now?
What happens when bitkeeper is gone (very soon now, right?)

To whom do I submit patches?

AFAIK almost all patches from http://www.246tnt.com/mpc52xx/ now in
vanilla kernel. Except, bestcomm, certainly :(.

P.S. Sylvain, what did you planned do with bk/git problem?

FEC is missing too.

Is anybody even working on bestcomm at the moment?

Cheers,

It may be Dale Farnsworth or smb. quietly in Freescale.

I sent patches to Sylvain in August 2004 with 5200 FEC support,
including my rewrite of the bestcomm FEC code.  I've bugged him
about it a few times, and I don't know why he hasn't made it available.
I haven't done much with the 5200 since then.  I'm traveling now and
have some other pressing issues, but I'll try to post what
I have in the next couple of weeks.

Dale, don't worry, Sylvain public your patches in himself src tree
(http://www.246tnt.com/mpc52xx/) at August/September,2004.
But, after that, OCP infra was dropped in kernel, and, hence, this
driver was not sent to Andrew Morton (Bestcomm stuff, until now, OCP
depended). And no one find time to convert Bestcomm to platform bus
model :(.

I planned start this job at July/August, so if someone wish to do it NOW
(June) - welcome.

Thank you Andrey, and my apologies to Sylvain.  I didn't realize that
they were available.  I'll take a look at converting to the platform bus
model, but it will be at least a week before I start.

Hi everyone

Following the obvious demand for it :

rsync://gitbits.246tNt.com/gitbits/linux-2.6-mpc52xx.git
http://gitbits.246tNt.com/gitweb.cgi?p=linux-2.6-mpc52xx.git;a=summary

Hopefully the server is setup correctly ...
It's not _heavily_ tested but it seems to works fine in the few test I made.

What in there :
 - I2C patches that are already sent upstream but not yet in Linus tree
 - Change of the mpc52xx uart device name and device ids to a range in
   the low density serial port major. Also it's now named ttyPSC? so
   you need to update you kernel command line (else you won't see any
   console). Note that the ids and names choosed are NOT YET OFFICIAL,
   I just included it in this release because some people were seeing
   conflict with the other ids. So the name and ids may change ...
 - Some other patches that will soon be sent upstream, just waiting
   for you to test see if it has any negative impact.
 - FEC and BestComm rewrite from Dale, with some improvement. For eg,
   the FEC task now handle misaligment so the manual alignment code
   has been removed, ...


Why is not bestcomm upstream already :
 There are a lot of minor stuff I don't like currently about it. The
most big part are : it mixes phys and virt address without any care, and
the fec driver needs improvement for the phy handling and for the dma
activity handling. I started working on some of this issues but I got
reassigned to more pressing matters ... The result was never published
because for now the only thing it does well is break everything ;)
 If someone wish to clean all that before I come to it, he's welcome
to contact me for info/ideas I had while working on it.


What is gonna be added "soon" :
 I'd say PIO IDE. But several people sent me a different version, so
I'll look into them and test them but probably not before next week.



Sylvain

PS: Does any one knows how to change the commit text in git/cg when
committed ? I realized I put "ppc:" at someplaces and "ppc32:" at others
and it's not coherent ...

And there was much rejoicing...  (hooraaaay)

Thanks Sylvain, I'll give it a try on Monday.
