Marius Strobl aa785996fd - Make better use of the global chosen, memory and mmu handles instead
of obtaining them over and over again and pretending we could do
  anything useful without them (for chosen this includes adding a
  declaration and initializing it in OF_init()).
- In OF_init() if obtaining the memory or mmu handle fails just call
  OF_exit() instead of panic() as the loader hasn't initialized the
  console at these early stages yet and trying to print out something
  causes a hang. With OF_exit() one at least has a change to get back
  to the OFW boot monitor and debug the problem.
- Fix OF_call_method() on 64-bit machines (this is a merge of
  sys/dev/ofw/openfirm.c rev 1.6).
- Replace OF_alloc_phys(), OF_claim_virt(), OF_map_phys() and
  OF_release_phys() in the MI part of the loader with wrappers around
  OF_call_method() in the sparc64. Beside the fact that they duplicate
  OF_call_method() the formers should never have been in the MI part
  of the loader as contrary to the OFW spec they use two-cell physical
  addresses.
- Remove unused functions which are also MD dupes of OF_call_method().
- In sys/boot/sparc64/loader/main.c add __func__ to panic strings as
  different functions use otherwise identical panic strings and make
  some of the panic strings a tad more user-friendly instead of just
  mentioning the name of the function that returned an unexpected
  result.
