- Make all IOBusDevices use the same code.
- Log error if 4 least significant bits of offset are not zero.
- Correctly byte swap the value before passing it to the IOBusDevice.
- When reading, duplicate the bytes in a word or dword like a real Power Mac does.

54bda0ea95 pci: Change pci_conv_rd_data unaligned.
pci_conv_rd_data can be used to handle unaligned or 64-bit accesses in mmio regions if it's modified to include the next 32-bit value.
For pci config accesses, grackle repeats the 32-bit value. bandit uses a seemingly random number for the next 32-bit value, but we'll make it work like grackle.

6d23e18c11 pci: Add PCI CardBus bridge.
PCCard is used by PowerBook G3 Wallstreet in Open Firmware 2.0.1.
CardBus is probed in New World Macs starting from at least Open Firmware 4.1.9f1 sometime after Open Firmware 3.1.1.

- Create PCIBase from common stuff in PCIDevice.
- Add PCIBridgeBase. These have a primary bus number, secondary bus number, and subordinate bus number which are used to determine if PCI type 1 config cycle should be passed.
- Change PCIBridge to use PCIBridgeBase instead of PCIDevice.
- Add PCICardBusBridge which uses PCIBridgeBase.

35c86ad6bf Clean up #includes
Result of running IWYU (https://include-what-you-use.org/) and
applying most of the suggestions about unncessary includes and
forward declarations.

Was motivated by observing that <thread> was being included in
ppcopcodes.cpp even though it was unused (found while researching
the use of threads), but seems generally good to help with build
times and correctness.

f61854a0ae Add has_io_space flag.
PCIDevice
- supports_io_space method now uses a flag has_io_space which is automatically set for PCI bridges or PCI devices that have an I/O BAR.

atirage
- Devices that have I/O BARs don't need a supports_io_space method.

mpc106
- Devices that don't have I/O methods don't need a supports_io_space method.

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.
