[U-Boot] [ANN] U-Boot v2017.05-rc2 released

Hey all,

It's release day and v2017.05-rc2 is out. I think my patchwork queue is looking good currently. I have some outstanding removal patches to take from Masahiro related to architectures that I removed as promised. The release is bigger than I really wanted, but since I was on vacation for most of the normal -rc1 window, stuff came in that would have come in then now, instead. Things are on track for -rc3 on the 1st.

Thanks all!
