[yocto] edison/denzil patches (post-1.1.2 and 1.2.1)

[McClintock Matthew-B29882]

Josh, Scott:

I've pushed a set of patches for edison/denzil branch - and I may push
a few more still to:

http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=mattsm/edison
http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=mattsm/denzil

These are all cherry-pick's and most applied cleanly and a few had
some minor cleanups. Please consider these for after the point
releases. I will continue to push to these branches and rebase these
branches off the official upstream trees as well.
