Thanks - it's been due to the broad meaning of the word "support". Thus indeed I should have been more precise and write something like "end-user board support by the OS" or similar.

@Rarok

The difference is the availability to end-users: for example, there is the MorphOS version for PowerUp on the one hand, which is freely available for registered PowerUp-users, although without customer support, and on the other hand also an internal MorphOS version for Efika (as a study, to demo the possibility to bring MorphOS also to this platform), which is not publically available. Currently there seem to be no plans to fine-tune and release this basic Efika port, though.
