The linker script bit is a noop, as f2a7a5c23d81 stopped using the
section defined in the linker script.

The comment about FSP was from map_debug_areas in
platforms/ibm-fsp/common.c. I assumed that Ben had the traces in a
defined area for it to be mapped properly. But I could be interpreting
the intent of that wrong.>
