I'm curious, this one never went in. I'd like to know if I'm not understanding CONFIG_SYS_TEXT_BASE completely. thanks.

What is the "start address"? I would say that "_start" defines the start address, i. e. the entry point into the U-Boot code where the CPU starts execution after a reset. But this is on most systems NOT CONFIG_SYS_TEXT_BASE. CONFIG_SYS_TEXT_BASE is the start address of the text segment. - as the name suggests. Guess that should be fixed... Best regards, Wolfgang Denk
