There is a PCI bridge(Tsi310) between the MPC8548 and a VIA southbridge chip. The bootloader sets the PCI bridge to open a window from 0x0000 to 0x1fff on the PCI I/O space. But the kernel can't set the I/O resource. In the routine pci_read_bridge_io(), if the base which is read from PCI_IO_BASE is equal to zero, the routine don't set the I/O resource of the child bus. To allow the legacy I/O space on the VIA southbridge to be accessed, use the fixup to fix the PCI I/O space of the PCI bridge.
