The subsystem has 32 KB of L1D configurable SRAM/Cache and 512 KB of L2 configurable SRAM/Cache. This subsystem has a CMMU but is not used currently. The inter-processor communication between the main A72 cores and the C711 processor is achieved through shared memory and a Mailbox. Add the DT node for this DSP processor sub-system in the common k3-j721e-main.dtsi file.
