Hi Khaled,

> Do I have to add a context for every type of memory?

I would say so. Yes.

The "easy" way:
    In context_read_mem you can implement depending of the type (aka 
switch type ==> specific code for your type of memory).

The better way:
    Use the context_dispatcher and the context_set_interface.
You define an interface per context type (secure, non secure, ...).
This way, you can isolate better the code for the various access types.

Hope it helps,
Xavier.
