Actually, the SheevaPlug has a Marvell-designed CPU core, which doesn't have anything to do with ARM9-the-implementation (which is an implementation of ARM-the-spec by ARM-the-company) (note the intentionally confusingly chosen terminology here). The SheevaPlug CPU core is sometimes compared to ARM926, though, since that's ARM-the-company's ARM-the-implementation that it is most similar to in terms of software visible features. Both ARM926 and the SheevaPlug CPU core conform to ARM-the-spec version 5. _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
