What device are you using and what version of U-Boot? Some of our U-Boot 
versions are quite old and some boards have seen significant changes in 
U-Boot functionality over the years.

I've also seen boards vary in how sophisticated their boot scripts in 
EEPROM/Flash memory are. I expect that many board manufacturers don't 
care how well their boot scripts work because the user can just 
reprogram the board to do what ever is required.

Maybe adding a suitably sophisticated boot.scr to the U-Boot package 
itself is a reliable way to solve this problem.
