The iMX53 security manual and multimedia ref manual states that there is a configurable set of registers in the CSU that control watermark regions on the M4IF.
I am grepping thru genode code but can't find this code. Is there some module/driver that handles these registers?

Hi Earlence,
You can find an implementation of m4if into os/src/server/tz_vmm/imx53/m4if.h. Thus, for example, main.cc file (same directory) makes use of _m4if.set_region(...,...); function to configure secure ram region for Secure World.

Hi,
I can't seem to find where the actual ARM code is that manipulates these registers. Where is the implementation of this interface?
