Misc board updates:
- Greg added a handful of boards to KS8695 (since he has stepped up to
maintain it).
- Qualcomm has added DT-only board support for a couple of their newer SoCs.
- misc other updates for Samsung and Freescale boards.

When a user program crashes due to an exception, the kernel can

sometimes helpful for debugging but serves no purpose on a

production system. Most people should say N here.

In addition, you need to pass user_debug=N on the kernel command

line to enable this feature. N consists of the sum of:

1 - undefined instruction events
