0bad71a347 Make all OF client interface calls return the maximum kind of
does-not-exist error when no client interface module is installed instead
of dereferencing NULL pointers. This eases implementation of platforms
that may or may not have Open Firmware.

054e5dcbe4 Change the argument type to OF_call_method to take an array of cell_t
instead of unsigned longs to prepare for platforms where they are not
the same.

8297758a22 Prepare and extend OFW layer for FDT support.
o Let OFW_INIT() and OF_init() return status value.

o Provide helper routines for 'compatible' property handling.

o Only compile OF and OFW code, which is relevant in FDT scenario.

o Other minor cosmetics

4a26780b9a Pull OF_quiesce() out of the MI Open Firmware layer and entirely into
PPC ofw_machdep.c, in recognition of its state as a machine specific hack.

79bf3fcd18 On PowerMac11,2 and (presumably) PowerMac12,1, we need to quiesce the
firmware in order to take over control of the SMU. Without doing this,
the firmware background process doing fan control will run amok as we
take over the system and crash the management chip.

This is limited to these two machines because our kernel is heavily
dependent on firmware accesses, and so quiescing firmware can cause
nasty problems.

acb97117e3 Fix the OFW interrupt map parser to use its own idea of the number of interrupt
cells in the map, instead of using a value passed to it and then panicing if it
disagrees. This fixes interrupt map parsing for PCI bridges on some Apple
Uninorth PCI controllers.

91416fb268 Modularize the Open Firmware client interface to allow run-time switching
of OFW access semantics, in order to allow future support for real-mode
OF access and flattened device frees. OF client interface modules are
implemented using KOBJ, in a similar way to the PPC PMAP modules.

Because we need Open Firmware to be available before mutexes can be used on
sparc64, changes are also included to allow KOBJ to be used very early in
the boot process by only using the mutex once we know it has been initialized.

nxge: cast page size fragments down to (int). If the vm's demand paging
PAGE_SIZE is ever too big for that, we've got far bigger problems.
ofw: move va_start() a little earlier. gcc-4.2 doesn't like us modifying
the last arg before the va_start().

838f76c0a9 - Restore the machine independency of sys/dev/ofw/openfirm.{c,h} by
moving OF_set_mmfsa_traptable() (SUNW,set-trap-table with the two
  arguments used here is specific to sun4v) to MD code.
- In sys/dev/ofw/openfirm.h remove prototypes for unimplemented
  functions and unused Solaris compatibility macros.

4cc1860f9b 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)
