[PATCH RTEMS 7/7] libtests/openfirmware: Added a testsuite for openfirmware

Hello,

I think the big question is: Should we make that a public API and keep
it in cpukit or should we make it a BSP support code and move ti to the
bsps/shared section?

Sebastian and Gedare: Like Niteesh said: There have been some different
directions in the past. Which one should be the target?

Best regards

Christian
