To me, these patches need further work.

* Many types seem to be used incorrectly (e.g. uint32_t instead of size_t).

Symptom of this presumed incorrectnesses are the amount of casts being 
used in address arithmetic. If the types were correct, most of the cast 
should not be necessary.

* There are local extern vars to share vars between files.

As mentioned several times before, this means, these works do not 
implement a proper API.

* The copyrights are questionable and possibly incorrect:

Most files state "Copyright OAR 1989-2012".
Have these files been derived from older files in RTEMS? If so, the 
files they have been derived from should better be mentioned somewhere.
Are these files new? Then these files _are_ copyrighted "2012 only" by 
their respective authors due to legal constraints.

Minor issue:

* Formating issues, such as tabs in Makefile.ams, etc.
