[RFC 3/5] board: starfive: support Milk-V Mars board

[E Shattow]

P.S. Found the longer description at
https://github.com/milkv-mars/mars-buildroot-sdk/commit/d381610c92827de01b25843786012351b3f35519
as follows: "if configured as 24c04, its address will occupy 0x51,
conflicting with the RTC chip pcf85063 on the IO-Board. Refer to:
Documentation/misc-devices/eeprom.rst". What does that even mean, it is for
Raspberry Pi Compute IO carrier only?
