There is no such faeature on that board, nor on any of a number of
other 85xx boards I have access to.

Is this also the cause why the Linux reboot ommand does not work?
If so, I wonder what has changed, because this used to be working in
older versions of the kernel? I did not attampt a full git bisect,
but from some old images I still found it appears it must have been
broken between 2.6.16 ("reboot" in Linux works fine) and 2.6.27
("reboot" does not work any more) - so probably this was part of the
arch/ppc => arch/powerpc rework.
Is there any specific reason we don't use the good old approach of
triggering an unhandled machine check exception?
Best regards,
Wolfgang Denk
