Hey, I'm attempting to make a simple reboot feature on Freescale's iMX53-QSB. I'm currently working using the tz_vmm example. So, I understand that the way to achieve that on this board is through the watchdog timer, I followed the Linux kernel code that does this, and implemented a kernel module

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 stru
