The binary is built alongside the TFA, OPTEE and A72 SPL binaries and included in the tispl.bin FIT image. The R5 SPL loads the DM binary at 0xA0000000 address, based on the value used in the FIT image build script. The DM binary though is an ELF image and not a regular binary file, and so is processed further to load the actual program segments using the U-Boot's standard ELF loader library. The DM binary does leverage a certain portion of DDR for its program segments, and typically reserves 16 MB of DDR at 0xA0000000 with the 1st MB used for IPC between Linux and the remote processor, and remaining memory for firmware segments. This can cause an incomplete loading of the program segments if the DM binary is larger than 1 MB, due to overlap of the initial loaded binary and the actual program segments. Fix this by using the address 0x89000000, which matches the current "addr_mcur5f0_0load" env variable used by R5 SPL before the DM firmware inclusion into the tispl.bin.
