From: Suman Anna <s-anna@xxxxxx>
The CMA reserved memory nodes have been added for both the IPUs and
the DSP1 remoteproc devices on the DRA72 EVM rev C board, and assigned
to the respective rproc device nodes. These match the configuration
used on the DRA72 EVM board. Both the CMA nodes and the corresponding
rproc nodes are also enabled to enable these processors on the
DRA72 EVM rev C board.
