Preventing the Expansion Pak from being utilized about libdragon HOT 3 OPEN

This may make more sense as a compile-time flag, but overall I think this is a solid suggestion.

from libdragon.

the above suggestion is a quick hack but it's not sufficient to really prevent libdragon from using > 4 MiB. In fact, the stack pointer is set in entrypoint.S depending on the amount of memory detected by IPL3 (written at 0x80000318), which is also used by get_memory_size().

The easiest way to really test a 4MiB configuration is to add these lines at the top of entrypoint:

li t0, 4*1024*1024
sw t0, 0x80000318

If we want to turn this into a feature, one idea that comes to mind is to set some special bit in the header, and read that in entrypoint.S. This can then be set via a new command line flag by n64tool, and in turn exposed as an option via a Makefile variable by n64.mk.

UPDATE Apr 2024: The suggested change isn't relevant anymore in the preview branch, because the entry point does things differently with the open source IPL3.

Compile time would work as well, but I'd think that a developer would need to rebuild Libdragon themselves, right?
