With the following add to my defconfig：
+CONFIG_MMC_IO_VOLTAGE=y
+CONFIG_SPL_MMC_IO_VOLTAGE=y
+CONFIG_MMC_UHS_SUPPORT=y
+CONFIG_SPL_MMC_UHS_SUPPORT=y
+CONFIG_MMC_HS400_ES_SUPPORT=y
+CONFIG_SPL_MMC_HS400_ES_SUPPORT=y
+CONFIG_MMC_HS400_SUPPORT=y
+CONFIG_SPL_MMC_HS400_SUPPORT=y

I can see HS400 with mmc ifnfo， but no HS400ES？Maybe the emmc on
the board does not support HS400ES，but I don't have datasheet about the emmc to check it.

With some test , HS400 seems work fine on these two boards,  I think I can enable it in the next version.
