Each cluster is equivalent to an Mailbox IP instance on OMAP platforms. Add all the Mailbox clusters as their own nodes under the MAIN NavSS cbass_main_navss interconnect node instead of creating an almost empty parent node for the new K3 mailbox IP and the clusters as its child nodes. All these nodes are marked as disabled, and they need to be enabled along with the appropriate child nodes on a need basis. NOTE: The NavSS only has a limited number of interrupts, so all the interrupts generated by a Mailbox IP are not added by default. Only the needed interrupts that are targeted towards the A53 GIC will need to be be added later on when some sub-mailbox child nodes are added.

The parent mailbox cluster nodes are enabled and the interrupts associated with the Mailbox Cluster User interrupt used by the sub-mailbox nodes are also added. The GIC_SPI interrupt to be used is dynamically allocated and managed by the System Firmware through the ti-sci-intr irqchip driver. The sub-mailbox nodes utilize the System Mailbox clusters 1 and 2. These sub-mailbox nodes are added to match the hard-coded mailbox configuration used within the TI RTOS IPC software packages. The Cortex R5F processor sub-system is 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 from cluster 0 is used in case of Lockstep mode.

Each cluster is equivalent to an Mailbox IP instance on OMAP platforms. Add all the Mailbox clusters as their own nodes under the MAIN NavSS cbass_main_navss interconnect node instead of creating an almost empty parent node for the new K3 mailbox IP and the clusters as its child nodes. All these nodes are marked as disabled, and they need to be enabled along with the appropriate child nodes on a need basis. NOTE: The NavSS only has a limited number of interrupts, so all the interrupts generated by a Mailbox IP are not added by default. Only the needed interrupts that are targeted towards the A72 GIC will need to be be added later on when some sub-mailbox child nodes are added.

These include the R5F remote processors in the dual-R5F cluster (MCU_R5FSS0) in the MCU domain and the two dual-R5F clusters (MAIN_R5FSS0 & MAIN_R5FSS1) in the MAIN domain; the two C66x DSP remote processors and the single C71x DSP remote processor in the MAIN domain. The parent mailbox cluster nodes are also enabled. The sub-mailbox nodes utilize the System Mailbox clusters 0 through 4. These sub-mailbox nodes are added to 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. The sub-mailbox node for the first R5F core in each cluster is used in case of Lockstep mode. NOTE: The GIC_SPI interrupts to be used are dynamically allocated and managed by the System Firmware through the ti-sci-intr irqchip driver. So, only valid interrupts (each cluster's User 0 IRQ output) that are used by the sub-mailbox devices are enabled. This is done to minimize the number of NavSS Interrupt Router outputs utilized.
