57e6e90002 Add support for the CUDA_RESTART_SYSTEM command
There are cases where when it's necessary (e.g. given uninitialized NVRAM,
the Beige G3 with the 10.2 install CD inserted will update the boot
device and restart to boot from it).

Restart support was done by wrapping the ppc_exec function in a loop and
checking for a restart power off reason. We also need to disconnect all
event listeners, since they will be recreated when the machine is
re-initialized.

fb0396923f Fix dma STORE_QUAD and LOAD_QUAD.
When fetching DMA command, make sure to convert little endian fields to host endianness (i.e. don't use memcpy).
When fetching DMA command, return the host address of the DMA command for LOAD_QUAD. Maybe this address should be cached whenever this->cmdptr changes?
When fetching DMA command, return whether the DMA command is writable.
For LOAD_QUAD, pass the address of the DMA command to xfer_quad.
Always log unexpected DMA command values.
Write full 32-bit value for LOAD_QUAD.
Write reqCount to resCount.

6503a300cc Add PCI interrupt method.

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.

For example, Old World Macs have versions of Open Firmware that don't support 512 MB BARs correctly. They may attempt to set such a BAR to 0x90000000 (a 256 MB boundary) instead of 0xA0000000 (the next available 512 MB boundary).

We now respond to the switch to device handler ID 4 and the register 1

We don't yet use the extra precision bits in the register 0.
