Yes, it is. Actually only  very  few  systems  use  memory  with  SPD

You should implement a proper initialization function for your memory

This depends on your hardware (type of memory etc.).

Please note that such questions ore of topic here. You will  probably
receive more / better response on the u-boot-users mailing list.
