I think we can improve this to provide rationale if data abort/ other
causes for the hang. But in this case, I am not sure it might help -
what we need to add is "boot reason" information probably. It does look
to me that a reset took place (u-boot hooks up it's own handlers for
irq,fiq,abort etc, but they were'nt triggered) - so either kernel abort
took place and a wdt trigger caused x-loader to come up in some
unexpected configuration that it could'nt handle OR a reset of somesort
took place.
