6075124f5d Move the EOI logic when starting ithreads into intr_machdep instead of
relying on it as a side effect of PIC_MASK() in the PIC drivers, and add
an inmplementation of assign_cpu() for the kernel interrupt layer.

033a2ddfa0 Add support for the Keywest I2C controller in Apple uninorth northbridges.
Although the Keywest registers have only 1 byte of content, they are
secretly 4-byte registers, which became apparent from them moving on the
big-endian Uninorth version of the controller.

071d45eec9 Change the default interrupt polarity on PowerPC systems from high to low.
On Apple systems at least, all the level interrupts are wired active low.
Before this change, our PIC programming only worked because Apple hardware
ignores the interrupt polarity bit on all interrupts except IRQ 0.

bbf5ab2a39 Get nexus(4) out of the RTC business. The interface used by nexus(4)
in Open Firmware was Apple-specific, and we have complete coverage of Apple
system controllers, so move RTC responsibilities into the system controller
drivers. This avoids interesting problems from manipulating these devices
through Open Firmware behind the backs of their drivers.

6a3018e7cf MFp4:
Introduce ATA_CAM kernel option, turning ata(4) controller drivers into
cam(4) interface modules. When enabled, this options deprecates all ata(4)
peripheral drivers (ad, acd, ...) and interfaces and allows cam(4) drivers
(ada, cd, ...) and interfaces to be natively used instead.

As side effect of this, ata(4) mode setting code was completely rewritten
to make controller API more strict and permit above change. While doing
this, SATA revision was separated from PATA mode. It allows DMA-incapable
SATA devices to operate and makes hw.ata.atapi_dma tunable work again.

Also allow ata(4) controller drivers (except some specific or broken ones)
to handle larger data transfers. Previous constraint of 64K was artificial
and is not really required by PCI ATA BM specification or hardware.

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.

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