Which kernel tree for future 8xx development?

Which kernel tree for future 8xx development?

[David Jander]

Hi,

Which (of the many) is the most recommended 2.4.x tree for mpc8xx devices 
(specially the MPC852T). We are developing our own board-support stuff and 
drivers (it's a custom board designed by us).
Currently we have linuxppc-2_4_devel from DENX cvs and linuxppc-2_4_devel from 
bitkeeper, which seems to be a newer kernel version, but with much less 
different boards supported and less features for motorola powerpc processors. 
What's the status of CPM driver stuff for instance?

We started on DENX kernel sources and switched to bitkeeper because of some 
misinterpreted advice I received from this list about an unrelated problem, 
only to find apparently less mpc8xx support.

Now I am observing myself doing apparently absurd things as for example taking 
arch/ppc/8260_io/cpm_spi.c from DENX and putting it into arch/ppc/8xx_io/ 
from bitkeeper and hacking until it works (again). It still doesn't. Where on 
earth is the original driver (which was for MPC860, not MPC8260)!??

Before we port all of our stuff once again from one tree to another, can 
someone please give me a good advice on which way to go now and in forseeable 
future? 
One day I'd like to be able to make all our board-support stuff into something 
useful for others and go beg for inclusion in the main sources.... but where?

Greetings,

That's probably arch/ppc/8xx_io/cpm_spi.c from our old linux-2.4
kernelk tree.

I cannot answer this question - maybe once there  is  a  clear  split
between  stable  and  development  kernel  trees again. At the moment
there is only chaos.
