** pcibus_setup():
|
|
** Probes for a pci system.

** pcibus_read():
|
|
** Read a long word from the pci configuration space.
|
|
** Requires a tag (from pcitag) and the register

|
|
** pcibus_write():
|
|
** Writes a long word to the pci configuration space.
|
|
** Requires a tag (from pcitag), the register number
