svn commit: r333955 - in head/stand: common ofw/libofw sparc64/loader

New Revision: 333955
URL: https://svnweb.freebsd.org/changeset/base/333955

Log:
  - Unbreak booting sparc64 kernels after the metadata unification in
    r329190; sparc64 kernels are always 64-bit but with that revision
    in place, the loader was treating them as 32-bit ones.
  - In order to reduce the likelihood of this kind of breakage in the
    future, #ifdef out md_load() on sparc64 and make md_load_dual() -
    which is currently local to metadata.c anyway - static.
  - Make md_getboothowto() - also local to metadata.c - static.
  - Get rid of the unused DTB pointer on sparc64.
