[U-Boot] [ANN] U-Boot v2017.11 is released

Hey all,

I've released v2017.11 and it's now live on git and FTP and ACD (along with PGP sig file).

We've had another good all-around release, and I like it.

The current schedule is that v2018.01-rc1 will be tagged on December 4th, with -rc2 on the 18th, -rc3 on January 1st and the release on January 8th. I plan to continue to and be more strict post -rc1 than I have historically been and contain -rc2/-rc3 to fixes only.

Thanks again everyone!
