Looks like the at91sam9261 uses the same SMC core as at32ap700x, we  
should look into using the same driver for both archs. I already have  
at32_smc in p4 to do bus managment and attach childs but no setup code  
(already done in uboot for what i need).

What about using hints more for device wiring instead of .c code like  
i did for avr32?
