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.

2b2250b149 - Re-write OF_decode_addr() with a bus-neutral approach, adding support
for nodes hanging off of Central (untested), FireHose (untested) and
  PCI (tested) busses.
- Add an additional parameter to OF_decode_addr() which specifies the
  index of the register bank to decode.

These should allow to eventually add support for the Z8530 hanging off of
FireHose to uart(4) and to write support for PCI-based graphics adapters.

b7b6c9e6fa - Make OF_getetheraddr() honour the "local-mac-address?" system config
variable. If set to "true" OF_getetheraddr() will now return the unique
  MAC address stored in the "local-mac-address" property of the device's
  OFW node if present and the host address/system default MAC address if
  the node doesn't doesn't have such a property. If set to "false" the
  host address will be returned for all devices like before this change.
  This brings the behaviour of device drivers for NICs with OFW support/
  FCode, i.e. dc(4) for on-board DM9102A on Sun machines, gem(4) and hme(4),
  regarding "local-mac-address?" in line with NetBSD and Solaris.
  The man pages of the respective drivers will be updated separately to
  reflect this change.
- Remove OF_getetheraddr2() which was used as a stopgap in dc(4). Its
  functionality is now part of OF_getetheraddr().

ec6a729924 Some integrated Davicom cards in sparc64 boxes have an all zeros
MAC address in the EEPROM, and we need to get it from OpenFirmware.
This isn't very pretty but time is lacking to do this in a better
way this near 5.2-RELEASE.  This is a RELENG_5_2 candidate.

2ec1dc3639 Add function OF_decode_addr(). This function obtains the physical
address of the device identified by its phandle_t by traversing OFW's
device tree. The space and address returned by this function can
subsequently be passed to sparc64_fake_bustag() to construct a valid
tag and handle for use by the newbus I/O functions.

Use of this function is expected to be limited to pre-newbus access to
devices, such as consoles and keyboards.
