The sub-mailbox nodes utilize the System Mailbox instances 5 and 6. These sub-mailbox nodes are added to match the hard-coded mailbox configuration used within the TI IPC 3.x software package. The Dual-Cortex M4 IPU1 and IPU2 processor sub-systems are assumed to be running in SMP-mode, and hence only a single sub-mailbox node is added for each. All these sub-mailbox nodes are left in disabled state, and should be enabled (and modified if needed) as per the individual product configuration in the corresponding board dts files.
