Yup, that's good as long as you can avoid exceptions. In u-boot, we
get interrupts from USB , so this caused NOR u-boot to crash when USB
was inserted, because one would usually have released the AUX button
at that time.

That's why we have to remap the whole address range there. It helped
that the CPU has this simple mapping originally made for WinCE.
Otherwise, a full MMU setup would have been necessary.

Sometimes, we get lucky ;-)
