You can use the article from the Compulab wiki:

http://compulab.co.il/workspace/mediawiki/index.php5/CM-FX6:_U-Boot:_Creating_a_bootable_SD_card

This article assumes that both SPL and U-Boot reside on a single
binary at the right offsets. The following article describes the
steps for creating this joined image:
