3 /* Reconfigure all I/O base address registers for a range of PCI busses

5  * adding an offset. This involves adjusting the base and limit registers
6  * of PCI-PCI bridges, too.
7  *
8  * RESTRICTIONS: 'offset' must be 4k aligned (PCI req.); no argument check
9  * on the bus numbers is done.
10  *
11  * RETURNS: 0 on success and a number > 0 indicating the number of
12  * non-32bit bridges found where the offset couldn't be added.
13  * Devices behind such a bridge are not accessible through I/O
14  * and should probably be switched off (not done by this code).
