Yes, the secure ram is separate from the ordinary DRAM.
But, access to it is address based via ARM AXI.

My design has a trusted L4re-App.
And i want to link the trusted app alone to the secure ram.
I argue that ordinary DRAM is easy to read out for an attacker that has 
local access to the platform.
The secure ram is less easy to read-out, so the trusted app would be 
more secure.
