Sorry, but I don't want to have this output.  It would be always be
printed for all systems booting from NOR flash, where the copy
operation is absolutely normal.

Also, on all PowerPC systems it is absolutely normal that you must
load the image to a different address in RAM, because otherwise you
would overwrite the exception vectors and thus crash U-Boot.

What you are trying to "warn" about is an absolutely normal use case,
and there is no reason for additional output.

Yes, there may be systems that could work more efficiently, but there
are many areas where you can optimize (starting with the Linux image
building).

Sorry, but NAK.


Best regards,

Wolfgang Denk
