The eMMC vendor is correct, the MMC card and chip level stuff is very similar, and uses the same signalling and protocols for the most part. There are some slightly different commands being used to talk to the card and initialize things.

stm32f7xx_hal_mmc.c and stm32f7xx_hal_sd.c are very similar, and both sit on top of the stm32f7xx_ll_sdmmc.c code.

The ST code has several issues the need to be remediated to be workable with most eMMC chips.
