svn commit: r326384 - head/stand/powerpc/kboot

[Warner Losh]

Author: imp
Date: Thu Nov 30 05:01:56 2017
New Revision: 326384
URL: https://svnweb.freebsd.org/changeset/base/326384

Log:
  Use const pointers to avoid casting away constness.
  
  The host_open interface was a legitimate mismatch to the userboot
  function, while the other pointers didn't need to be non-const.
  
  This makes the powerpc warning free again.
