These nodes are assigned to the respective rproc device nodes as well. The first region will be used as the DMA pool for the rproc device, and the second region will furnish the static carveout regions for the firmware memory. The current carveout addresses and sizes are defined statically for each device. The C71x DSP processor supports a MMU called CMMU, but is not currently supported and as such requires the exact memory used by the firmware to be set-aside.
