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

Dear "sywang",

I want to do pci configuration in the function 'board_init_f'. How to do this?
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?
Could I call the function "pci_init" in the function 'board_init_f' or add the function "pci_init" into the function array " init_sequence "?
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,
