IMX6QP: Maximum supported DDR size

[kishorr]

As per IMX6QP data sheet, the maximum supported DDR size is 3840MB. I would like to know if this is the max DDR that can be used with imx6qp.

Thanks

Hello,

  let me remind, for 32-bit addresses 4GB is maximum address area.

But some address range should be left for peripherals.  

Regards,

Yuri.
