Hi Charles,
I have encountered similar problems before. The error might happen while compiling MLO for OMAP platforms. Check the Makefile under "u-boot/spl/board/" or other spl-related Makefiles. There might be some unnecessary .o files outside the
#ifndef CONFIG_SPL_BUILD obj-(CONFIG_BLABLABLA...) += <something>.o obj-(CONFIG_BLABLABLA...) += <something>.o ...... #endif
put the .o files which necessary for u-boot.img but not for MLO inside.
