Error cross-building Linux 2.6 for 8xx

Alex,
The earlier 2.6.9 kernel version do not compile right on MPC8xx, but the
2.6.10-rc3 does compile without problem (in my case using a cross gcc
v3.4.3). You may want to try this version first...
As many people explained, the linux kernel on MPC8xx is not totally
working for now. But you can still play arround with it and contribute
to the porting :)
Regards,
Guillaume.
