If its in NOR flash, for example, one would add a partition of suitable size to put the data in.

I'm not sure the toolchain can handle that and I am sure that method is not welcome in the repository (800kb binary --> several MB c-source)... > How is this case typically handled? > Have a look at the code to handle FPGA images, you can probably even reuse or share code with there.
