Wolfgang,
thanks for the hint - unfortunately the issue is not solved, yet. Obviously I've missed something...
U-boot is working fine with both 256MB and 512MB RAM. The kernel crashes with memory > 256MB.
Do I need to set up a 2nd BAT for mapping main memory before booting linux in any case ?
Do you now of any kernel related issues/missing configs ? I know this is off-topic to this list - but maybe you can help me out.
regards, Andre

Is this a general or known issue ?
You may want to search for CONFIG_VERY_BIG_RAM and CONFIG_MAX_MEM_MAPPED, see for example "lib_ppc/board.c".
Best regards,
