8xx v2.6 TLB problems and suggested workaround

[Joakim Tjernlund]

Hi Marcelo

Reading your report it doesn't sound likely but I will ask anyway:
Is it possible that the problem you are seeing isn't caused by the
"famous" CPU bug mentioned here:

The DTLB error handler needs DAR to be set correctly and since the
dcbX instructions doesn't set DAR in either DTLB Miss nor DTLB Error you
may end up trying to fix the wrong address.
