Russell, this patch is in the patch tracker with Rob's ACK from
the DT side, do you think you could apply it?

For Nomadik I actually only need the write-allocate-override
flag to be selectable, so if you think it is increasing complexity
too much I'd be happy to make a diet version which only
adds this flag.
