Unfortunately this is not saying i2c address and also how to handle stacked solution. I have told to Linus what Xilinx is using for FMC connector present on the most of xilinx development boards. These on board FMC eeproms contain information in FRU format. Also there incomplete support fmc support in the kernel in drivers/fmc which was added by Alessandro Rubini in 2013. At least these eeprom could reuse FRU data format.
