I doubt that OAR has a copyright for contents of this new file, but if
they have one, then the license change from the standard RTEMS license

If you need to define _init() and _fini() here, then something is wrong
with the GCC configuration for this target. For example:
nm /opt/rtems-4.11/lib/gcc/sparc-rtems4.11/4.9.2/crti.o
00000000 T _fini
00000000 T _init

It would be nice to have implementations of the above two functions at
least for all new ports. See test sptests/spcontext01. It ensures that
the context switch and interrupt code works now and later if some makes
a modification.
The Doxygen comment copy and paste in the cpu.h files is a real mess in
general. It would be better to mention only the architectures specifics
in this file, e.g. references to the ABI documents.
