771997501f - Add a device interface method for bus_get_resource_list() and use
bus_generic_rl_release_resource() for the bus_release_resource() method
  instead of a local copy.
- Correctly handle pass-through allocations in fhc_alloc_resource().
- In case the board model can't be determined just print "unknown model"
  so the physical slot number is reported in any case.
- Add support for blinking the 'Cycling' LED of boards on a fhc(4) hanging
  of off the nexus (i.e. all boards except the clock board) via led(4).
  All boards have at least 3 controllable status LEDs, 'Power', 'Failure'
  and 'Cycling'. While the 'Cycling' LED is suitable for signaling from
  the OS the others are better off being controlled by the firmware.
  The device name for the 'Cycling' LED of each board is /dev/led/boardX
  where X is the physical slot number of the board. [1]

8e1ff29d07 Minor changes:
- Use FBSDID.
- Remove unused macro.
- Use auto-generated typedefs for the prototypes of the bus and device
  interface functions.
- Terminate the output of device_printf(9) with a newline char.
- Honour the return values of malloc(), OF_getprop(), etc.
- Use __func__ instead of hardcoded function names.
- Print the physical slot number and the board model on attach.

26280d88d7 - Introduce an ofw_bus kobj-interface for retrieving the OFW node and a
subset ("compatible", "device_type", "model" and "name") of the standard
  properties in drivers for devices on Open Firmware supported busses. The
  standard properties "reg", "interrupts" und "address" are not covered by
  this interface because they are only of interest in the respective bridge
  code. There's a remaining standard property "status" which is unclear how
  to support properly but which also isn't used in FreeBSD at present.
  This ofw_bus kobj-interface allows to replace the various (ebus_get_node(),
  ofw_pci_get_node(), etc.) and partially inconsistent (central_get_type()
  vs. sbus_get_device_type(), etc.) existing IVAR ones with a common one.
  This in turn allows to simplify and remove code-duplication in drivers for
  devices that can hang off of more than one OFW supported bus.
- Convert the sparc64 Central, EBus, FHC, PCI and SBus bus drivers and the
  drivers for their children to use the ofw_bus kobj-interface. The IVAR-
  interfaces of the Central, EBus and FHC are entirely replaced by this. The
  PCI bus driver used its own kobj-interface and now also uses the ofw_bus
  one. The IVARs special to the SBus, e.g. for retrieving the burst size,
  remain.
  Beware: this causes an ABI-breakage for modules of drivers which used the
  IVAR-interfaces, i.e. esp(4), hme(4), isp(4) and uart(4), which need to be
  recompiled.
  The style-inconsistencies introduced in some of the bus drivers will be
  fixed by tmm@ in a generic clean-up of the respective drivers later (he
  requested to add the changes in the "new" style).
- Convert the powerpc MacIO bus driver and the drivers for its children to
  use the ofw_bus kobj-interface. This invloves removing the IVARs related
  to the "reg" property which were unused and a leftover from the NetBSD
  origini of the code. There's no ABI-breakage caused by this because none
  of these driver are currently built as modules.
  There are other powerpc bus drivers which can be converted to the ofw_bus
  kobj-interface, e.g. the PCI bus driver, which should be done together
  with converting powerpc to use the OFW PCI code from sparc64.
- Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take
  advantage of the ofw_bus kobj-interface and simplify them a bit.

63ec9d57c9 Implement interrupt resource allocation and setup. Set the interrupt
group number properly based on the board id.  Perform dummy reads of
registers after writing to flush the hardware write buffers.

This gets the soon to be committed zs attachment working.

012d9539bf Add drivers for the central and fhc busses found in enterprise class
UltraSPARCs, and an eeprom attachment for fhc, which allows the date
to be set properly on these machines.  Central is a wierd bus which
seems to only ever have 1 fhc attached to it.   FHC (FireHose Controller)
is another wierd bus with various things on it depending where its attached.
The fhc attached to central has eeprom and zs, and the fhcs which attach
directly to nexus have simm-status, environment and other nodes, none of
which I'll probably ever have documentation for.

Thanks to Ade Lovett for providing access to an 8 cpu e4500.
