I plan to submit a patch for it, so I wonder if we still number > the SD card as mmc1 even if there is no emmc. Yes, please For Milk-V Jupiter, it has emmc slot despite plug the module in or not, so it make sense to name it as mmc1, in other words, the board do support emmc in the hardware level For future board, if the board has no emmc feature design in, then I'd be fine with name it as mmc0 or mmc1, shouldn't be much difference.. -- Yixun Lan (dlan)
