Please explain why you would want to do this.  To me it makes no
sense.  Either U-Boot knows the correct memory size, then it should
pass it to Linux.  Or it does not, then U-Boot should be fixed.

Also, I object that your implementation is ARM specific.  If such a
feature gets added, it should be architecture independent.

Thanks.
