Wolfgang, 

Thanks for your feedback. 

Because the CPU-hang issue when pci_init still puzzle me, I want to check if
the issue is caused by relocate_code, in spite of the very probability. 

Do you have any suggestions about how to identify the root cause of PCI Init
configuration hang?  

Thanks!
Shuyou

Why would you want to do that? Why cannot you wait until U-Boot has
relocateditself to RAM so you have full access to all resources?

This might be difficult, as you still have a very limted runtime
environment only, with just a minimal stack, without writable data,
without valid BSS.

Best regards,
