I looked into the documentation but I can't find a command which copies an image from one address to another.
you mean 'cp' ?
Well, not exactly. cp doesn't know anything about the size of an image and is, compared to a simple memcpy or even an optimized version of memcpy, painfully slow which would eat up my expected performance improvements. A quick hack showed that a "imcpy" command could save me some 400ms on boot time which is about 50% of the total time spend in u-boot.
