-**	The following functions are provided by the pci bios.
-**	They are used only by the pci configuration.
-**
-**	pcibus_setup():
-**		Probes for a pci system.
-**		Sets pci_maxdevice and pci_mechanism.
-**
-**	pcibus_tag():
-**		Creates a handle for pci configuration space access.
-**		This handle is given to the read/write functions.
-**
-**	pcibus_ftag():
-**		Creates a modified handle.
-**
-**	pcibus_read():
-**		Read a long word from the pci configuration space.
-**		Requires a tag (from pcitag) and the register
-**		number (should be a long word alligned one).
-**
-**	pcibus_write():
-**		Writes a long word to the pci configuration space.
-**		Requires a tag (from pcitag), the register number
-**		(should be a long word alligned one), and a value.
-**
-**	pcibus_regirq():
-**		Register an interrupt handler for a pci device.
-**		Requires a tag (from pcitag), the register number
-**		(should be a long word alligned one), and a value.
