Where DDR Ram gets initialised when there is no SPL

Hi ,

 

The normal boot process is , SPL is loaded to the SRAM and during the execution of the SPL  DDR Ram gets initialized.

Once the DDR is initialized , u-boot /kernel  is loaded to DDR Ram.

Now SPL is no longer in use and CPU directly loads the u-boot to DRAM. Now question is , where the DDR Ram gets initialized ?  IMX can load u-boot only when the DDR ram is initialized. Where this initialization happens ?

Please suggest.
