I'm trying to get the ppc6xx_defconfig booting on any 8641 (74xx/e600)

the .dts it works.  Otherwise it hangs at but and looks to be crashed in 
the serial driver due to accessing memory at 0.

I've tried the same .dts (w/'simple-bus') using the  
mpc8641_hpcn_defconfig and things work.

The Xilinx folks hit something similar.  ns16550 nodes get matched if
the parent claims simple-bus.  If extra stuff needs to be done to use
that port, then bad things happen.
