Dear All,


Problem : We are using discrete DDR3 on chip, why  "DRAM:  Initializing....using SPD".


I have  done #undef CONFIG_DDR_SPD and written QCVS DDR3 generated parameter in config file.


Please check and verify attached t208xrdb.h config file.


Any other configuration is required to configure
