Moving from 2.4 to 2.6 kernel

[Chris Dumoulin]

I'm looking into getting a BDI 2000 so I can start stepping through and 
see what is going on.

I looked at the ML300 and V2Pro code in the arch/ppc/platforms/4xx 
folder, but I did not use any of that in my code. It looks like this is 
intended to be used with the BSP that is generated by Xilinx Platform 
Studio. I've tried generating the BSP this way, but the generated code 
is obviously not a complete patch to port Linux to your hardware, and I 
figure that by the time I figure out what I do/don't have to add, I 
might as well write the whole thing by myself. Have you had success 
integrating the automatically generated BSP from Xilinx Platform Studio?

Regards,
Chris
