imx6 chip expertise,

I have an imx6dl customer board refer from imx6dlsabresd, the MMC i used is connect to MX6_PAD_SD1, and in uboot I set the dev_no=0 so it can find the mmc 0, what is the correct parameter transfer to kernel, => printenv mmcdev
=> printenv mmcroot
mmcroot=/dev/mmcblk0p2 rootwait rw
If this is wrong, then what is the correctly mapping?
