Is the EEPROM required for DDR4, and if so, how and where can it be moved?

1) The SPD EEPROM is required by the JEDEC standard, but there should be a way to make DDR functional without the EEPROM.  How can this be done? 

 

2) What is the EEPROM on the LS1043ARDB being used for and how can the function be moved to another memory location such as flash memory?

 

3) How painful would it be to move the EEPROM data into boot code and is there a configuration that does this already without having to make kernel and uboot changes?

 

Thanks you.
