At the top of the .x file it says it's for "normal"
executables, so that's the one I picked. You don't want to run
the risk of ending up with an abnormal executable...

Ah! msp1 and msp2?
That's what I was trying to find a few days ago. Since those
generic CPU types are already there, that's 80% of what I
wanted. The rest is just a bit of documentation on how to
modify a linker script. For the parts I've used all that
involves is changing the size/location of the flash and RAM
sections at the top of the file -- there are probably other
changes I haven't tripped over for some parts.

Yup.

That's fine.
