As you say, I don't think the space issue is much of a problem.
I'm more worried about the replacement of one crazy model that has
problems due to linker subtlety with _another_ one.
Your genksyms.c change is not exactly obvious. I looked at it, and my
brain just shut down. Why both the
LONG(0x%08lx);
_and_ the
"%s__crc_%s = 0x%08lx;\n"
in the linker script? I'm sure there's a good reason, but I'd like to
see a more explicit explanation fo what the generated linker script
does and what the rules are.
