how to dynamically change DDR size after booting up ?

[pisces]

Hi,

Our bsp is based on imx6sx processor, this bsp need to support two hardware platform.

The difference of this two hw platform is DDR size, one is 512MB, another is 1GB.

So, after powering up, the u-boot needs to dynamically change the DDR size according to the hw board id.

Does everyone knows how to change DDR size dynamically after powering up ?

Thanks.
