P.S. Found the longer description at https://github.com/milkv-mars/mars-buildroot-sdk/commit/d381610c92827de01b25... 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?

The same vendor (Milk-V) U-Boot change is present on their branch for Mars CM Lite (which despite the naming has more in common with Pine64 Star64 than Mars); However on visual inspection the silkscreen markings are for 24c04. See: [Photo flatbed scans of Mars CM Lite 4GB rev 1.01]( https://github.com/geerlingguy/sbc-reviews/issues/22#issuecomment-1872478605). Can this be determined at runtime, or I must trust that this is not a wrongly marked chip?
