SDTI is the Coresight component which is the subgroup of PrimeCell. So my question is still valid. How does the 'amba' interface handle the fragmented memory regions? I understand that for the right Coresight IP it should not happen and the whole register space should be continous and ended by the Peripherial and Component Ids. If I use SDTI module (window) memory region as a static definition inside driver will my patch be accepted?
