Check the OF_getprop() return value before proceeding. Allocate only as
much space as needed for the mode buffer. Use strcmp, relying on OF giving
back NULL terminated strings.

Check the real-mode? OF property to find out whether we operate in real or
virtual mode. In virtual mode we have to do memory mapping. On PowerMacs it is
usually false while on pSeries we have found that it is true. The real-mode?
property is not available on sparc64.

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.

- 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.

Sync the styles of sys/boot/ofw/libofw/openfirm.c and
sys/dev/ofw/openfirm.c with themselves, with each-other
and with style(9).

Remove unused variables.

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

All hell breaks loose if the loader image is released before
jumping to the kernel. Another bug exposed by removing the
1:1 BAT mapping. Sparc64 doesn't do this either.

Compile tested on: panther (sparc64). Code built, but not used, on sparc64.

Convert to __FBSDID.

Major rework of how we copy data into kernel space.

We now talk to the memory and mmu instances directly rather than using the
OpenFirmware "claim" method.

Add OF_claim_virt() and OF_release_phys().

Make the openfirmware entry point function pointer non-static so that it
can be passed to the kernel.

- Use the cell_t type definition for Open Firmware arguments in
combination with requisite casts as this avoids fatal side
effects on 64-bit architectures.
- Add the OF_alloc_phys function.

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.

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)

"Ok, my loader's now up to putting up a prompt. It probes disks partially
but can't boot from them yet."

Thanks to Stephane Potvin for the some of the code in this set.
