✨ DESCRIPTION ✨

so the sximmc driver? she provides support for the MMC/SD/SDIO controller that's integrated on Allwinner A1X/A20 SoCs. that's it, that's the assignment, and she ate 💅

and then there's the sdmmc(4) subsystem, which is the one actually doing the work of performing SD/MMC transactions — it's how we communicate with the MMC, SD, SDHC, or SDIO devices that get inserted into the SD slot. main character energy honestly, the slot's got the whole little ecosystem going on 🔥
