fd05df3205 Allow the interrupt controller to be probed - this picks up the 
Heathrow PIC, while not affecting the OpenPIC.

bd687ebf3b A module to handle the interrupt controller on Heathrow/Paddington 
MacIO chips, found on older Mac G3's.

da5dcc52fc Vastly simplify the macio ATA attachment, now that the register file 
indirection is handled in the ATA common code.

5f9dfe1e17 Remove sparse addressing hack. The macio ATA driver no longer requires 
this.

0b86d93fe6 - Add PCI ID for Paddington i/o controller, used in old G3's 
- Add ID for the Intrepid i/o controller, used in new 12"/17" PowerBooks
- put IDs in chronological order

658930c2c0 Oops. Include opt_ddb.h. 2003-02-06 11:07:39 +00:00

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.

24b51ed09e If a device tries to allocate an interrupt that's not on it's resource list, 
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.

44956c9863 Remove M_TRYWAIT/M_WAITOK/M_WAIT. Callers should use 0. 
Merge M_NOWAIT/M_DONTWAIT into a single flag M_NOWAIT.

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.

98f8e6c099 Driver for the Apple UniNorth Host-PCI bridge. 
This is in a PowerMac-specific subdirectory as it is hoped that we will support
more than just the PowerMac platform.
