Imx6QP:emmc boot with DMA in uboot

Dear my friends

      
     I would like to modify the uboot emmc driver so that it supports dma boot ,because i think it takes a lot of time to load the kernel and ramdisk image
     In fact, my real goal is to save boot time, I have cut off a lot of useless drivers, but still need about 480ms time. So I hope uboot starting from emmc using DMA. At the same time I need to know if it can save some time
     Ihope someone can give me some help or some of the views, I can do to achieve the goal .


     Thank you
