[PATCH v2 0/4] board: starfive: add Milk-V Mars CM support

[Heinrich Schuchardt]

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.

v2:
	fix typos in get_mmc_size_from_eeprom() description
	rename spl_fdt_fixup_marc() to spl_fdt_fixup_mars_cm()
	rename device-trees for Mars CM and Mars CM Lite
	change model and compatible properties
	refer to tio as tool for booting via UART
	describe how to update serial number
