This is a very bad idea as it will open a window brick your system at
each and every "saveenv" command.
I strongly recommend not to do that.

If you stop doing 1., all other problems will just disappear.

If you really insist in such an unreliablke configuration, a custom
linker script would IMO be better, as it would make the image layout
more visible.
