Now I wonder if a similar thing might be done in start.S, so that the [re] mapped size of flash complies with what is defined in the config file? Either from flash size, or from the _PRELIM_* settings that are already there? Instead of current status quo of hardwired to 8M flash size?

start.S is definitely not the place for (re)mapping flash. Please read the README. Only after relocation to RAM the flash seize can be determined, and only then the final mapping can be set up. Just like it is done now - at list in all sane ports.

Dropped because I'll rather pull from your git repo. Thanks.
Best regards,
