svn commit: r283033 - head/sys/arm/arm

New Revision: 283033
URL: https://svnweb.freebsd.org/changeset/base/283033

Log:
  Do not set preload_addr_relocate for ARM.  Apparently there was a time
  when loader(8) passed physical addresses in loader metadata for arm, but
  that is no longer true; all metadata has already been adjusted to vitual
  addresses by loader.
  
  I can't track down the exact revision in loader where a change from physical
  to virtual metadata addresses happened.  The code involved is very twisty
  and complicated.  I suspect the change was an unintended consequence of the
  r247301, r247413, r248118 series of changes I made a couple years ago.
