i.MX53 TrustZone cross world interactions

Hey,

I'm using Freescale i,MX53 QSB. I'm trying to transfer data between the secure world and the normal world, at the moment, I manage to transfer data using the CPU registers (using Linux kernel module I wrote), and I manage to receive them on the hypervisor. I would like to transfer larger structure, for example a memory buffer, I'm allocating in the normal world kernel a buffer, I send the physical address (using __pa) to the secure world.

My question is, how in the Genode hypervisor I can access this memory address ? Any idea will be helpful

Thanks Ofer
