We take Linux Kernel as Poplar DTS upstream, and patch #1 sync up u-boot DTS with it, so that devices like MMC are available to use with u-boot driver model. Patch #2 adds Poplar mmc compatible to hi6220_dw_mmc driver, so that the driver can probe Poplar mmc device. And finally patch #3 cleans up the board level mmc initialization code, as they are not used any more.
