This stalled my background work on general RTEMS improvements (in this 
case the build system). I think the path is clear. We use source tree 
path regular expressions to assign source files to categories. The 
source tree path is determined for each symbol by the DWARF compilation 
unit information. The categories are defined in an INI file in 
rtems-tools for now. Maybe later it is places somewhere else.

I would like to continue now with the build system changes. This will 
break the coverage tool categories for some time.

Is there some documentation on how I can use the coverage tool? Which 
BSP is recommended for test runs?
