We came to the conclusion it is not possible to handle it. Something
to do with the MMU i think, but i don't remember. There is a thread in
the archive, and for the platform which i know is broken, the dts file
points to:

https://lists.debian.org/debian-arm/2012/08/msg00128.html

which contains instructions how to append a few bytes of code to the
front of the image to turn the cache off.
