svn commit: r260323 - head/sys/arm/tegra

[Ian Lepore]

Author: ian
Date: Sun Jan  5 16:45:34 2014
New Revision: 260323
URL: http://svnweb.freebsd.org/changeset/base/260323

Log:
  Eliminate use of fdt_immr_addr(), it's not needed for this SoC.  Convert
  to the newer arm_devmap_add_entry() routine for creating device mappings.
