With this series the Milk-V Mars CM board can be booted.
NVMe, SD-card, Ethernet, UART are working but not USB.
The first series Milk-V Mars CM Lite board (the version without eMMC) uses incorrect series numbers indicating eMMC presence. For these CONFIG_STARFIVE_NO_EMMC=y must be set to indicate that eMMC is not present.
Thanks to E. Shattow for all the helpful discussions. He figured out what needed to be patched in the device-tree.
