[U-Boot] pci bus scan in u-boot-1.0.2

[xiaoguizi007]

Hello,
 
        I'm tring using pci function of u-boot-1.0.2. But while the programm run into function pci_hose_scan_bus() in /drivers/pci.c, it looks like go to dead and will never run. So, I assert some debug infomation, and then get the problem,maybe it is pci_hose_##rw##_config_##size() function. Because this function will never return this time! 
         Can anybody help me!
     
Thanks a lot,
     Josh Wei
