The Milk-V Mars board is technically very close to the StarFive VisionFive 2 board.
With this patch series the VisionFive 2 U-Boot SPL will detect that it is running on a Milk-V board and patch the device-tree accordingly. This is the same approach that has been taken to handle the differences between the Visionfive 2 1.2B and 1.3A revisions.
For the mmc card-detect a separate patch has been created: https://lore.kernel.org/u-boot/20240328214615.21501-1-heinrich.schuchardt@ca...
