Limitations of entity-manager:FruDevice

[Patrick Venture]

Hi;

I don't know much about FRUs.  However, I know that for some eeproms
on the device-tree for my platform, the default eeprom driver instance
isn't correct and I need to explicitly use 24c64.

For entity-manager, I can add the type and it'll do the right thing.
However, when FruDevice runs first and populates the FRUs, it doesn't
seem to detect the difference in the eeproms.  I don't know enough (as
previously stated) to jump into fixing this, so I wanted to check if
this was a known limitation (presumably) and whether there was a plan
to fix it?
