svn commit: r329991 - head/sys/dev/uart

New Revision: 329991
URL: https://svnweb.freebsd.org/changeset/base/329991

Log:
  Teach the Arm pl011 driver to attach to a SBSA uart. This is defined in
  the Server Base System Architecture to be a subset of the pl011 r1p5. As
  we don't use the removed features it is safe to just attach to the existing
  driver as is.
