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.

Regars,
