The final 128KB in SRAM is reserved by default for DMSC-lite code and secure proxy communication buffer. The memory region used for DMSC-lite code can be optionally freed up by secure firmware API[1]. However, the buffer for secure proxy communication is not configurable. This default hardware configuration is unique for AM64.
Therefore, indicate the area reserved for DMSC-lite code and secure proxy communication buffer in the oc_sram device tree node.

You may actually want to reorder so that this patch is first.
