No, I don't think I made changes to let CPU know about this when it branches to the boot vector.
After I posted this message, I learned the reset vector for the PPC architecture lies at 0xFFF00100. Does it mean the u-boot has to start at the address 0xFFF00000? If not, how can I let CPU know to look for u-boot at this new address? Please let me know if it is documented somewhere.
