StarFive VisionFive 2 has two versions, 1.2A and 1.3B, each version of DDR capacity includes 2G/4G/8G, a DT can not support multiple capacities, so the capacity size information is recorded to EEPROM, when DDR initialization required capacity size information is read from EEPROM.

If there is no information in EEPROM, it is initialized with the default size defined in DT.
