[U-Boot] [ANN] U-Boot v2014.07-rc4 released

Hey all,

I've pushed v2014.07-rc4 out to the repository and tarballs should exist soon.

So I think I've picked up most of the outstanding patches that are bugfixes now. I know there's still some FAT related changes to go pick up (and I intend to shortly), and Albert should have one more PR for u-boot-arm.

As always, if anything is broken please speak up.

Thanks all!
