Does stm32_sdmmc2.c contain methods for emmc only?

[Mark81]

Looking at this code:

https://github.com/ARM-software/arm-trusted-firmware/tree/af1ac83e0fa4e77aad13e1e8e47b6fcafeb17dbc/drivers/st/mmc

I don't understand if the methods are named after the sdmmc2 bus of the MPU (#1 for sd card, #2 for emmc) or it's just a suffix without any special meaning. In other words, they are used also to access to the sd-card?
