These nodes are assigned to the respective rproc device nodes, and both the IPU and DSP remote processors are enabled for this board. The current CMA pools and sizes are defined statically for each device. The starting addresses are fixed to meet current dependencies on the remote processor firmwares, and will go away when the remote-side code has been improved to gather this information runtime during its initialization. An associated pair of the rproc node and its CMA node can be disabled later on if there is no use-case defined to use that remote processor.
