svn commit: r242389 - head/sys/mips/cavium

[Juli Mallett]

Author: jmallett
Date: Wed Oct 31 04:23:36 2012
New Revision: 242389
URL: http://svn.freebsd.org/changeset/base/242389

Log:
  If the CF physical base is 0, attach no CF devices.  This fixes a warning
  about a 0 passed to cvmx_phys_to_ptr on systems without a CF interface,
  such as the RSYS4GBE.
