[PATCH 1/5] Let CPU/BSP Fatal handler have access to source
Daniel Hellstrom
daniel at gaisler.com
Wed Jun 4 09:23:34 UTC 2014
Without the source the error code does not say that much.
Let it be up to the CPU/BSP to determine the error code
reported on fatal shutdown.
This patch does not change the current behaviour, just
adds the option to handle the source of the fatal halt.
