Hi Yifeng,
Since "mmc: rockchip_sdhci: add phy and clock config for rk3399", my RockPi 4b device can't boot off of eMMC. It will start tpl/spl and then fail:
U-Boot TPL 2021.10-rc1-gac804143cf-dirty (Aug 11 2021 - 10:02:07) Channel 0: LPDDR4, 50MHz BW=32 Col=10 Bk=8 CS0 Row=15 CS1 Row=15 CS=2 Die BW=16 Size=2048MB Channel 1: LPDDR4, 50MHz BW=32 Col=10 Bk=8 CS0 Row=15 CS1 Row=15 CS=2 Die BW=16 Size=2048MB 256B stride lpddr4_set_rate: change freq to 400000000 mhz 0, 1 lpddr4_set_rate: change freq to 800000000 mhz 1, 0 Trying to boot from BOOTROM Returning to boot ROM...

If I revert these changes, all is well:
