imx8mm - Pin bank and offset mapping

Hello,

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?

 

Thanks!
