51d163d3e9 Convert PowerPC AIM PCI and nexus busses to standard OFW bus interface. This
simplifies certain device attachments (Kauai ATA, for instance), and makes
possible others on new hardware.

On G5 systems, there are several otherwise standard PCI devices
(Serverworks SATA) that will not allow their interrupt properties to be
written, so this information must be supplied directly from Open Firmware.

66821a4c67 Set sc_psim so that the openpic core can correct the off-by-one
error in the number of IRQs that PSIM gives us.

d6f5929710 Add support for the BUS_CONFIG_INTR() method to the platform and to
openpic(4). Make use of it in ocpbus(4). On the MPC85xxCDS, IRQ0:4
are active-low.

05c62b81bf Add PIC support for IPIs. When registering an interrupt handler,
the PIC also informs the platform at which IRQ level it can start
assigning IPIs, since this can depend on the number of IRQs
supported for external interrupts.

77d40ffd98 Revamp the interrupt handling in support of INTR_FILTER. This includes:
o  Revamp the PIC I/F to only abstract the PIC hardware. The
   resource handling has been moved to nexus, where it belongs.
o  Include EOI and MASK+EOI methods to the PIC I/F in support of
   INTR_FILTER.
o  With the allocation of interrupt resources and setup of
   interrupt handlers in the common platform code we can delay
   talking to the PIC hardware after enumeration of all devices.
   Introduce a call to powerpc_intr_enable() in configure_final()
   to achieve that and have powerpc_setup_intr() only program the
   PIC when !cold.
o  As a consequence of the above, remove all early_attach() glue
   from the OpenPIC and Heathrow PIC drivers and have them
   register themselves when they're found during enumeration.
o  Decouple the interrupt vector from the interrupt request line.
   Allocate vectors increasingly so that they can be used for
   the intrcnt index as well. Extend the Heathrow PIC driver to
   translate between IRQ and vector. The OpenPIC driver already
   has the support for vectors in hardware.

a4954466bd - Use the rman_get_* functions instead of reaching into struct resource.
- Remove __RMAN_RESORUCE_VISIBLE again. It's no longer required either
  because of the above change or because struct rman is no longer hidden.

739af9bcb5 Make the OpenPic driver bus-independent, with attachments for
the MacIO chip and PSIM's IOBus. Bus-specific drivers should
use the identify method to attach themselves to nexus so
interrupt can be allocated before the h/w is probed. The
'early attach' routine in openpic is used for this stage
of boot. When h/w is probed, the openpic can be attached
properly. It will enable interrupts allocated prior to
this.
