Board-specific GPIO setup code

On the Wandboard (IMX6Q SoC), there is a WiFi module connected via SDIO 
that requires a reset procedure to enable it. This would be board 
specific setup, but gpio_* functions can't be used in 

What would be the correct place to perform the reset code (basically a 
series of gpio calls) to reset the WiFi controller or should it be done 
earlier in uboot?
