[U-Boot] [ANN] U-Boot v2014.04-rc2 released

Hey all,

I've pushed v2014.04-rc2 out to the repository and tarballs should exist soon.

The good news this time around is Masahiro did some more updates to the system and we're now building faster than before. This should be noticable in both the single config build and arch/soc/vendor/etc builds.

As always, if anything is broken please speak up.

Thanks all!
