HI Liu,
This is generic mmc.c, not dw_mmc.

In the mmc_select_hs400es function, mmc_set_card_speed(mmc, MMC_HS,

Also mention |mmc_select_mode_and_width()|, which already passes
|true| for HS400-ES.
The third parameter is set to true, but the judgment branch for the
hsdowngrade parameter does not include MMC_HS400_ES_SUPPORT.
Not a missing runtime if case - if (hsdowngrade) never checks the mode.
Modify the message.

Update this comment to mention HS400-ES as well.
