TZC380 on iMX6Q/7D: AXI ID and AID_WIDTH

Hi everyone,

I am trying to configure a TZASC (TZC380) in my secure kernel to prevent Linux and some DMA to mess with the secure part of DRAM. In the documentation, the FAIL ID register holds the identifier of the faulty master. The id n = AID_WIDTH-1 bit long, and represent the master AXI ID.

 

Where can I find the value of AID_WIDTH and a table listing the possible master AXI ID ?

 

Best regards,

Vincent
