Oh, I must have missed this request....

Anyhow, let me first explain the name...

bus_dmamap_create() creates a DMA map... as the name implies...

bus_dmamap_load() does the necessary machine-dependent magic, and
loads the map with the mapping.  I suppose one could call this
"binding a mapping" ... unload unloads the mapping from the map.

I guess I'm not really objecting to changing the names, tho...

It has never been my intention to have this interface write
board-level registers.
