One R5F cluster is present within the MCU domain (MCU_R5FSS0), and the other one is present within the MAIN domain (MAIN_R5FSS0). Each of these can be configured at boot time to be either run in a LockStep mode or in an Asymmetric Multi Processing (AMP) fashion in Split-mode. These subsystems have 64 KB each Tightly-Coupled Memory (TCM) internal memories for each core split between two banks - ATCM and BTCM (further interleaved into two banks). The TCMs of both Cores are combined in LockStep-mode to provide a larger 128 KB of memory. Add the DT node for the MCU domain R5F cluster/subsystem, the two R5F cores are added as child nodes to the main cluster/subsystem node. The cluster is configured to run in LockStep mode by default, with the ATCMs enabled to allow the R5 cores to execute code from DDR with boot-strapping code from ATCM. The inter-processor communication between the main A72 cores and these processors is achieved through shared memory and Mailboxes.
