Not necessaryly. You have not changed them, but who says they were correct before?
I am not sure, but before relocation it might have not mattered if they were
different. Just really check to make sure.

I can only advice a step by step approach: Take the at91sam9260ek port and
only change the bits that are different for 9263 and your board. I don't have any
9263 based board here, so I cannot point to a proven, working port for that SoC.
