you misread it.  the question is for people who have loaded u-boot, and then 
want to load another copy of u-boot into ram and then execute that directly.

so the question is "can u-boot be *started in ram*" and the answer is "no".  
normally u-boot is bootstrapped from non-ram storage (via a bootrom, or some 
bit of code being latched in at a hardcoded address, or some other cpu-specific 
magic).
