New Revision: 326840
URL: https://svnweb.freebsd.org/changeset/base/326840

Log:
  Allow bman-portals and qman-portals to attach to simple-bus
  
  Official Linux dts's put the individual portals under a simple-bus, rather
  than under a '*-portals' grouping.  This adds a hack to permit that, which
  gets us closer to using stock device trees for DPAA-based devices.
