bee24b166d Add method to attach PCI device with new name.
- Added an overloaded version of attach_pci_device which takes a suffix string that can be used to make a device name unique so that multiple devices of the same class can be added to a machine. The method returns a PCIDevice which can be easily used to attach more PCI devices if it is a PCIHost.

be45a6a020 Add PCI bridge and multi-function device support.
Add PCI bridge and multi-function device support.
Overview:
- A multi-function device is two or more PCIDevices with the same device number but one device is function zero (as with currently implemented PCIDevices) and the other functions have function numbers between 1 and 7. The device number and function number are properties of the PCIDevice's parent PCIHost connection.
- A PCIBridge is a PCIHost (it can connect child PCI devices) and a PCIDevice (it has config space, BARs, and expansion ROM).
- A PCIDevice has Type 0 header. It has 6 BARs.
- A PCIBridge has Type 1 header. It has 2 BARs. The config space registers beginning from offset 0x18 differ from those of a PCIDevice.

Possible future modifications:
- Add a PCICardBus class. It is a PCIHost. It has Type 2 header. It has one BAR. The first 20 bytes match Type 0 and Type 1 headers. These exist in New World Macs. They allow hot-plug of PCI devices.
- Split base PCI registers (first 16 bytes) into a PCIBase class. Type 1 and 2 have two or one BAR but I think all 6 BARs belong in PCIBase class anyway.
- Split PCIHost into two classes: Currently existing PCIHosts (Bandit, Grackle) are PCIHost and PCIRoot (they have the broadcast I/O requests functionality) while PCIBridge is PCIHost only - it can propagate I/O requests but does not originate the broadcast.
- pci_register_mmio_region should maybe return a pointer to a region struct so that it can be used for unregistering or modifying the region's range. This may be useful for PCI bridges which have ranges that may constrain memory BARs of their downstream devices.

PCIDevice
- Moved expansion ROM BAR handling to a separate function pci_wr_exp_rom_bar so that it can be used by both PCI devices and PCI bridges which have the ROM BAR in different locations. It now supports unmapping expansion ROM. Also made exp_rom_bar not writable if there's no ROM.
- Added num_bars field which specifies the number of valid BARs since Type 0, 1, and 2 headers have different number of BARs.
- map_exp_rom_mem now properly unmaps expansion ROM (using new function unmap_exp_rom_mem) before mapping it again.
- Added function set_multi_function which modifies hdr_type to indicate if a device has other functions. This is to be applied only to devices with function number 0.

PCIHost
- When attaching a PCI device, it will check if it's a multi-function device (there exists an attached function that is not zero) and adjust hdr_type of function 0 of the device accordingly.
- Attached PCI bridges are added to a list of PCI bridges attached to the host.
- Added pci_io_read_loop and pci_io_write_loop which loop through attached PCI devices to find one that will perform the action for the given I/O address without logging an error (since some other device might perform the action).
- Added pci_io_read_broadcast and pci_io_write_broadcast which are used by a PCI root (bandit/grackle). They will log an error if the action is not performed. They should probably do a machine check exception to match real Power Macs.
- pci_find_device (used by PCI root) will recursively find a PCIDevice for type 1 config register accesses.
- Logging from PCIHost now includes the name of the PCIHost instead of just "PCIHost" because there can be multiple PCI hosts.

PCIBridge
- Sets num_bars to 2 and hdr_type to 1.
- I/O ranges set in the config registers are handled correctly by pci_io_read and pci_io_write.
- Memory ranges set in the config registers do not currently affect memory mmio regions. It is assumed that Open Firmware and the OS will set the ranges and BARs correctly to allow all BARs to be accessed fully.

bandit, mpc106
- Bandit and Grackle now call pci_io_read_broadcast and pci_io_read_broadcast to pass I/O accesses to downstream PCI devices.
- Chaos is modified to work like Bandit even though it will never have PCI bridges attached or devices that support I/O accesses. It's simpler this way.

b472123746 Standardize PCIDevice slot_id for PCIHost.
PCIHost
- PCIHosts (bandit and grackle) now use device number and function number for identifying attached PCIDevices. A macro DEV_FUN is added to calculate this new slot_id. Bandit no longer uses IDSEL. Grackle no longer uses only device number.

machinecatalyst, machinegossamer, machinetnt
- Use DEV_FUN to attach PCI devices by device number and function number.

fd2e6c5b09 Fix ATIRage I/O accesses.
- Don't log anything if the I/O access is not for this device. A different device might handle it.
- Don't return true for I/O access if an I/O access is not performed. Otherwise the I/O access won't be passed to other devices.

2a64f547cc Add 64-bit BAR support.
While dingusppc only emulates 32-bit Macs (for now), it is possible for a 32-bit Power Mac to use a PCIe card that has 64-bit BARs.

finish_config_bars is added to scan the cfg values of the BARs and determine their type. The type is stored separately so that it does not need to be determined again.
The type can be I/O (16 or 32 bit) or Mem (20 or 32 or 64 bit). A 64 bit bar is two BARs, the second contains the most significant 32 bits.

set_bar_value uses the stored type instead of trying to determine the type itself. It is always called even when the firmware is doing sizing. For sizing, It does the job of setting the bar value so do_bar_sizing is now just a stub.

Every PCIDevice that has a BAR needs to call finish_config_bars after setting up the cfg values just as they need to setup the cfg values. Since they need to do both, maybe the cfg values should be arguments of finish_config_bars, then finish_config_bars() should be renamed config_bars().

fba2ff4231 Corrections for refactors.
- Macros need parenthesis to enforce operation order when expanded.
- Fix device and register numbers in log messages.
- Unmapped I/O space reads don't necessarily return 0xffffffff. That's only for config space reads. Just return 0. Unhandled I/O space read should probably cause a memory check (TEA - Transfer Error Acknowledge) exception as it does on a Power Mac 8600.
