I'd say anything that factorizes ARM code is a good thing. :)

However I'm not in favor of a CONFIG option that would force the board 
code to provide some functions just in odrer to override one, not if 
weak definitions can do a finer job. I am looking into that already for 
cache management function specialization, and it seems like there is the 
same kind of possibility here, with lib functions defined weak and the 
board code overriding the ones it deems necessary to.

I will look into it a bit more this morning.
