DMSC: Firewall Region requires specific configuration
The ECC Aggregator inside DMSC (DMSC0_ECC_AGGR) has an endpoint firewall which is used to protect this region. By default, this firewall blocks all the transactions except from the M3 core inside DMSC.
If another processor or endpoint needs to access DMSC0_ECC_AGGR region, software shall configure the firewall region with starting address 0x0 and end address 0xFFFF_FFFF, using the CBASS_FW_REGION_i_START_ADDRESS and END_ADDRESS registers associated with the DMSC0_ECC_AGGR region. This is the only allowable address configuration for this region.
