Merge tag 'chrome-platform-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/chrome-platform

Pull chrome platform updates from Olof Johansson:
 "Here's the branch of chrome platform changes for v4.4.  Some have been
  queued up for the full 4.3 release cycle since I forgot to send them
  in for that round (rebased early on to deal with fixes conflicts).

  Most of these enable EC communication stuff -- Pixel 2015 support,
  enabling building for ARM64 platforms, and a few fixes for memory
  leaks.

  There's also a patch in here to allow reading/writing the verified
  boot context, which depends on a sysfs patch acked by Greg"
