80bd99be33 Bring to working PIO state. 
- use correct rid when allocating PCI mem resource
 - ATA taskfile registers are indeed spaced 0x10 apart just like
 the Macio ATA cell. Adjust offsets in ATA channel struct.

321fd46031 Work-in-progress for the 'Kauai' ATA device in Mac notebooks. The 
device seems to be the macio ATA cell with a PCI front-end, and
has no relation to PIIX-style ATA/PCI devices.

475a183dd1 - remove trailing whitespace 
- fix compile warnings. badaddr() will go to a header file soon.

2894a94905 Use device alias "mpic" to locate the macio OpenPIC. This works 
on the new 12/15/17" PowerBooks that don't have the "interrupt-controller"
property underneath "/chosen", which was the previous way of
searching.

73cb337c32 Use a device identify entry point to attach to nexus, since the 
nexus code no longer searches for interrupt controllers.

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.

ithread_create() changes etc.  This should be mostly a NOP.

d674899b66 Add a driver that attaches to the gpio node of macio and allows you to enter 
DDB when the interrupt button (aka the "programmer's switch") is pressed.

This isn't unfortunately an NMI, but it's a handy way to get into DDB
quickly if needed.

assume that the child knows what it's doing and add it to the resource list.

fe5e7c6b2b Rework of how memory resources are discovered and dealt with in macio. 
- Store the OpenFirmware "reg" property in the macio ivars.
- Use a struct to define the structure of a "reg" property entry.
- Discover all memory ranges, not just the first.
- In ata_macio, manage our own range and hand out our own allocations using
  bus_space_subregion.
- Fix bus_space_subregion to handle subregions of sparse maps.

30081705c6 - Remove the ignore list and replace it with a quirk list of sorts. 
- Add a quirk type for devices whose interrupt properties are actually
  attached to their children.
- Flag the "escc" (zs-alike serial controller) device as having this quirk.
- Rework the interrupt discovery code to deal with devices that have more than
  one interrupt.
