4ca12119c3 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.

3fcef6d9c2 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.

188fbdbc6c Extend and improve MPC85XX Local Bus management.
- Make LBC resources management self-contained: introduce explicit LBC
  resources definition (much like the OCP), provide dedicated rman for LB mem
  space.

- Full configuration of an LB chip select device: program LAW and BR/OR, map
  into KVA, handle all LB attributes (bus width, machine select, ecc,
  write protect etc).

- Factor out LAW manipulation routines into shared code, adjust OCP area
  accordingly.

- Other LBC fixes and clean-ups.

- clean up registers usage
- improve comments to better reflect reality

f0e837432d Adapt parts of the sparc64 Open Firmware bus enumeration code (in particular,
the code for parsing interrupt maps) to PowerPC and reflect their new MI
status by moving them to the shared dev/ofw directory.

This commit also modifies the OFW PCI enumeration procedure on PowerPC to
allow the bus to find non-firmware-enumerated devices that Apple likes to add,
and adds some useful Open Firmware properties (compat and name) to the pnpinfo
string of children on OFW SBus, EBus, PCI, and MacIO links. Because of the
change to PCI enumeration on PowerPC, X has started working again on PPC
machines with Grackle hostbridges.

Sgtty is a programming interface that has been replaced by termios over

ioctl()'s that are implemented by this interface. The importance of this

9d3bb599b1 - bump __FreeBSD version to reflect added buf_ring, memory barriers,
and ifnet functions

- add memory barriers to <machine/atomic.h>
- update drivers to only conditionally define their own

- add lockless producer / consumer ring buffer
- remove ring buffer implementation from cxgb and update its callers

- add if_transmit(struct ifnet *ifp, struct mbuf *m) to ifnet to
  allow drivers to efficiently manage multiple hardware queues
  (i.e. not serialize all packets through one ifq)
- expose if_qflush to allow drivers to flush any driver managed queues

changes.

- ATAPI DMA is broken on Marcel's Mac Mini because we need an ATA SELECT hook

4efdef565f Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.
