please use sensible subject for the cover letter too. Ideally it should
start with the corresponding subsys name or otherwise point out the
target.

Up to now we have been using [1].  There is no way to switch to the
mentioned repo with no changelog information between them.

And anyway, as pointed out earlier, please steer your activities towards
implementation at [2]. Both "fastrpc" implementation are ugly,
AOSP-centric and must be dropped as soon as possible.
