This change starts with removing the effectively empty file timerdrv.h. The prototypes for benchmark_timer_XXX() were in btimer.h which was not universally used. Thus every use of timerdrv.h had to be changed to btimer.h. Then the prototypes for benchmark_timer_read() had to be adjusted to return benchmark_timer_t rather than int or uint32_t. I took this opportunity to also correct the file headers to separate the copyright from the file description comments which is needed to ensure the copyright isn't propagated into Doxygen output.
== Rhealstone Benchmark For RTEMS This is an implementation of the Rhealstone benchmarks for RTEMS. The Rhealstone metric is a set of benchmarks that aim to provide an independently verifiable objective measure of real-time performance in different systems. The Rhealstone metric is composed of six independent benchmarks, each of which measure an activity that is critical in real time systems: * Task switch time * Task preemption time * Interrupt latency time * Semaphore shuffle time * Deadlock breaking time * Intertask message latency An implementation of the Rhealstone metric allows for RTEMS performance to be compared with other real-time systems. The original proposal outlining the Rhealstone benchmark can be found http://collaboration.cmc.ec.gc.ca/science/rpn/biblio/ddj/Website/articles/DDJ/1989/8902/8902a/8902a.htm[here].
