Just to be clear, the upper layer of the EDAC driver will or will not
panic when a UE is detected on layerscape?

If there is no panic by the upper layer and no reset triggered by the
layerscape CPLD or memory controller, what happens on layerscape when
a UE is detected by the memory controller?

Forcing a UE by grounding a dataline caused a reset on layerscape
after a few seconds, but no panic. It is unclear why it reset, but it
appears as though a WDT was tripped. The UE was reported by EDAC and
seen in the log.
