Just to clear my question again: - It wasn't about the comment but concept behind Master/Slave terminology. - Why are we referring src and dest as Master and Slave. As there is nothing like that. - As pointed by Russell and me earlier: Probably it is for choosing the victim for reduction of width, in case src and dest addresses are misaligned to each other.
If what i understood is correct, then we should get rid of this routine or this master/slave terminology, as this is causing confusion.
