Could you please point out why is too tsi148-specific?
The point here is that the driver should know *nothing* about windows, etc. What it should just know is: - I want a mapping of a certain size to VME address X The struct provides exactly this.
Also, could you please send me (off-list) documentation of the Universe bridge? It'd be useful for the work on the generic layer.
