The PL08x has two bus mastering interfaces. They can be
connected to two separate busses and two adress spaces
even, usually that is not the case though.

This is not what the function is about... that's done by my
pl08x_select_bus() function.

To be clear, I was explaining what I percieved as a
question from Viresh about what the comment in this hunk of
the patch was about:

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.
