I was trying to setup some pins in uBoot and was trying to find the IO bank and offset mapping so I could make use of
IMX_GPIO_NR(bank, nr) to control the pin.
I didnt see anything in the reference manual and the imx dts files on the kernel side use this format
* The pin function ID is a tuple of
* <mux_reg conf_reg input_reg mux_mode input_val>
Also in the kernel is there a recommended place for board initialization or is it best to keep that in uboot?
