The dts file of the MediaTek MT8195 demo board has been updated to include new reserved memory regions. These reserved memory regions are: - SCP - VPU, - Sound DMA - APU.
These regions are defined with the "shared-dma-pool" compatible property. In addition, the existing reserved memory regions have been reordered by their addresses to improve readability and maintainability of the DTS file.
