The Keystone 2 66AK2L SoCs have 4 TMS320C66x DSP Core Subsystems (C66x CorePacs), each with a 1.0 GHz or 1.2 GHz C66x Fixed / Floating-Point DSP Core, and 32 KB of L1P & L1D SRAMs and a 1 MB L2 SRAM. Add the DT nodes for these DSP processor sub-systems. The processors do not have an MMU, and use various IPC Generation registers and shared memory for inter-processor communication. The aliases with a stem 'rproc' have also been added for all the DSPs, they provide a fixed remoteproc id to each DSP processor.
