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 .
