I see this message every time when I build the kernel.  I know it's
harmless, but is this something that can be "fixed"?  That is, can we
change some linker script (or whatever) to make 0x700000 the default
value?  Or maybe modify the wrapper script to just automatically find
the right spot without printing a message?
