svn commit: r189407 - in head/sys/dev: puc uart

[John Baldwin]

Author: jhb
Date: Thu Mar  5 16:43:33 2009
New Revision: 189407
URL: http://svn.freebsd.org/changeset/base/189407

Log:
  Add support for the single-port NetMos NM9835 serial adapter.  The puc(4)
  entry is a specific entry to override the generic NetMos entry so that
  puc(4) will leave this device alone and let uart(4) claim it.
