2023-09-20 Thread Andrew Jeffery
It appears some (many?) EEPROMs that implement 16-bit data addressing will accept an 8-bit address and clock out non-uniform data for the read. This behaviour is exploited by an EEPROM detection routine in part of OpenBMC userspace with a reasonably broad user base: https://github.com/openbmc/enti
