I updated:

Yes, I think this is more in line with:

https://docs.rtems.org/branches/master/user/installation/prefixes-sandboxing.html#project-sandboxing

In this manual:


|/bd/rtems/4.11.0/tools|
    Production prefix for RTEMS 4.11.0 compiler, debuggers and tools.
|/bd/rtems/4.11.0/bsps|
    Production prefix for RTEMS 4.11.0 Board Support Packages (BSPs).

What should be the content of "tools" and "bsps"?
