** 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.
