The commit adds the impelementation of ADAC protocol towards the
target side.
Following components are part of the commit:-
Core : ADAC protocol core
SDA : Secure Debug Agent
The commit also demonstrates the porting of a platform from
trusted-firmware-m. Corstone1000 platform is used for the purpose.
