Even if the 'dsp' node is disabled the memory intended to be used by the DSP is reserved. This limits the memory range suitable for CMA allocation. Thus disable the dsp_reserved node. DSP users need to enable it in parallel to the 'dsp' node. Signed-off-by: Alexander Stein <alexander.stein@ew.tq-group.com> --- Actually the location and size of DSP reserved memory is platform specific. But to be less intrusive, just disable the node. arch/arm64/boot/dts/freescale/imx8mp.dtsi | 1 + 1 file changed, 1 insertion(+)
