[Ian Lepore]

Author: ian

New Revision: 270076
URL: http://svnweb.freebsd.org/changeset/base/270076

Log:
  MFC r269607, r269698:
  
    Cache the imx6 SoC type in a static var so that it only has to be figured
    out by sniffing hardware registers once.
  
    Add a missing clock register definition.
