Thank you for driving the TH1520 support forward.
Locally I updated the Lichee Pi4A device-tree based on the Linux device-tree and built th1520_lpi4a_defconfig with
CONFIG_CMD_MMC=y CONFIG_MMC=y CONFIG_MMC_SDHCI=y CONFIG_MMC_SDHCI_SNPS=y
You can also enable following options: CONFIG_MMC_IO_VOLTAGE=y CONFIG_MMC_UHS_SUPPORT=y CONFIG_MMC_HS400_ES_SUPPORT=y CONFIG_MMC_HS400_SUPPORT=y
For HS400_ES mode also needs to add `mmc-hs400-enhanced-strobe` line to the emmc node in the Lichee's DT.
HS200/HS400/HS400_ES modes work fine with eMMC on my Lichee Pi4A board. MicroSD works fine at UHS SDR104 too.
Bus Speed for both devices is 198MHz
I tested reading from eMMC and SD-card as well as writing to SD-card and found no problems.

Thanks for testing!
