0003 /* Reconfigure all I/O base address registers for a range of PCI busses
0004  * (from and including 'bus_from' up to and not including 'bus_to').
0005  * adding an offset. This involves adjusting the base and limit registers
0006  * of PCI-PCI bridges, too.
0007  *
0008  * RESTRICTIONS: 'offset' must be 4k aligned (PCI req.); no argument check
0009  *          on the bus numbers is done.
0010  *
0011  * RETURNS: 0 on success and a number > 0 indicating the number of
0012  *          non-32bit bridges found where the offset couldn't be added.
0013  *          Devices behind such a bridge are not accessible through I/O
0014  *          and should probably be switched off (not done by this code).
