AM5718: How to understand DSP memory mapping？

When you build DSP code, config.bld may not have the final definition for memory map. It could be modified by other CFG file.

You can check the generated map file after the build to see the exact DSP memory map is defined and built by your DSP project.

When running Linux on A15, we have to carve out / reserve DSP memory from Linux Kernel using cma pool.

The memory reserved for IPU2/DSP1/IPU1 to used is defined in DTS file.

The memory sections defined in DSP memory map should reside within the memory range reserved by cma pool in DTS file.
