Add the reserve-memory nodes used by DSP when the rpmsg
feature is enabled.
These can be later used in a dsp node, like:
dsp: dsp@3b6e8000 {
compatible = "fsl,imx8mp-dsp";
reg = <0x3b6e8000 0x88000>;
mbox-names = "tx0", "rx0", "rxdb0";
mboxes = <&mu2 2 0>, <&mu2 2 1>,
<&mu2 3 0>, <&mu2 3 1>;
memory-region = <&dsp_vdev0buffer>, <&dsp_vdev0vring0>,
<&dsp_vdev0vring1>, <&dsp_reserved>;
status = "okay";
Drop this example from commit msg, useless and not really correct.
Ok, will drop it. But this is a correct example, is just incomplete.
};

Please test the patches before sending. This does not build.

I've tested on remoteproc tree, but it seems I missed a bracket when sending upstream. Sorry abut this, will fix it in v2.

Should I test this on other tree(s)?

Thanks,
Iulia

Best regards,
