Hi Kamlesh!

Add support for high security bootflow on am62 devices.
On HS devices, ROM and TIFS will protect the RAM regions with firewalls. This means the wakeup domain's SPL will need to move the stack and heap to HSM RAM to ensure it stays within its allotted memory regions.

Thanks for getting this fixed! Does TIFS drop the On Chip SRAM firewall completely once it's started? or only for the r5?
