I am going to be a heavy user of the Mailbox API. And I have reviewed
this API quite in detail. I pointed out many aspects that might have
worked for TI's usage but are not going to be work on many platforms
(including one of mine).  Suman and Loic also acknowledged most (if
not all) from 'generic' POV.  Here is the thread ...
   http://www.spinics.net/lists/arm-kernel/msg239433.html

Not to mean only talk and no do, I prepared another proposal that
addressed all the concerns shared so far in the RFC
http://www.spinics.net/lists/kernel/msg1523873.html (its not ready for
primetime yet)  And also converted the PL320 driver to the new API,
unlike the pulled patchset which leaves that out in the cold.
http://www.spinics.net/lists/kernel/msg1523874.html

Now, we could either call it (effectively the TI's framework with
quirks for STE) as the "Common API" and then dismantle and convert it
patch by patch (authors and I seem to agree many things need to be
changed and implemented).
  OR we do it reasonably right the first time even if that means yet
another release. IMHO we should go for slow but steady thing.

Hi Suman, Hi Loic,
   Please feel free to object to anything you think I might have
misrepresented. I am OK if you are not sure about my implementation
either - we could co-work on a new one.
