e7e5b53bf1 Replace index() and rindex() calls with strchr() and strrchr().
The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

4da7d606a2 Fix some memory management issues discovered when trying to boot the PPC
OF loader on systems where address cells and size cells are both 2 (the
Mambo simulator) and fix an error where cons_probe() was called before
init_heap() but used malloc() to set environment variables.

d6e6728367 - 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.

342a196627 Don't unconditionally compile-in the bcache code. It's only used on
i386/amd64 and pc98. Remove useless calls to bcache_init() from the
ia64 and sparc64 loaders, as well as from the OFW common code.

24ad8a9842 Instead of "OpenFirmware", "openfirmware", etc. use the official spelling
"Open Firmware" from IEEE 1275 and OpenFirmware.org (no pun intended).

19020b09b6 G5 support: handle the case where the OpenFirmware memory array uses
64 bits for the phys address, but only 32 for the virtual address.

5fe386cc27 - use correct pointer arithmetic in heapsize calculation
- handle multiple Ofw memory regions when determining mem size
- allow currdev to be set as a loader command-line option.
  parse() is used to allow future options to be processed.

73d398d702 Change the device path representation in libofw to use the full firmware
path, instead of an internal i386 specific one.  Don't try to interpret
a disklabel in ofw_disk.c, open the partition's device node directly and
let the firmware do it.  This fixes booting from a partition other than 'a'
on sparc64, which is needed to support more installation methods.

994f7977f1 Mega-patch for OpenFirmware loader support.
- Flesh out ofw_readin routine.
- Add OpenFirmware load and exec routines.
- Make sure memory allocation for the kernel is done correctly.
- Change the way the heap is allocated so as to make it easier to deallocate
  when we hand over.
- Add a command to print memory maps similar to the one for ia64.

With this patch, I can now load and hand over to a kernel on my iMac.  There
are some problems with OpenFirmware routines failing after the hand over that
still need to be addressed.

7d73a33303 OpenFirmware/PowerPC loader, part 2.
As of this patchset, the loader builds (under NetBSD/macppc), boots, interacts
and talks to BOOTP/NFS servers.

(main.c was moved from boot/ofw/libofw to boot/ofw/common but has no revision
 history)
