These include the R5F remote processors in the two dual-R5F clusters (MAIN_R5FSS0 & MAIN_R5FSS1) in the MAIN domain; and a M4 processor in the MCU safety island. These sub-mailbox nodes utilize the System Mailbox clusters 2, 4 and 6. The remaining clusters 3, 5 and 7 are currently not used, and so are disabled. Clusters 0 and 1 were never added to the dts file as they do not support interrupts towards the A53 core. The sub-mailbox nodes added match the hard-coded mailbox configuration used within the TI RTOS IPC software packages. The R5F processor sub-systems are assumed to be running in Split mode, so a sub-mailbox node is used by each of the R5F cores. Only the sub-mailbox node for the first R5F core in each cluster is used in case of a Single-CPU mode for that R5F cluster. NOTE: The cluster nodes only have the Mailbox IP interrupt outputs that are routed to the GIC_SPI. The sub-mailbox nodes' irq-id are indexing into the listed interrupts, with the usr-id using the actual interrupt output line number from the Mailbox IP.
